# How to Perform CPR on a Cat: Step-by-Step Guide ## Key Takeaways - Immediate CPR initiation is critical for cats in cardiac arrest (unconscious, not breathing, no heartbeat, pale/blue gums), as brain cell death begins within 3-4 minutes without oxygen. - CPR involves a combination of chest compressions (100-120 per minute, 1/3 to 1/2 chest width) and rescue breaths (1 breath every 5 seconds, gentle inflation to chest rise), with a cycle of 30 compressions followed by 2 breaths. - Correct hand placement for compressions is crucial: on the left side of the chest, just behind the elbow, or thumb-and-forefinger squeeze for very small cats, to avoid damaging internal organs. - Rescue breaths require closing the cat's mouth, forming a seal over the nose, and delivering a soft, steady breath for one second, observing for chest rise, to prevent lung rupture. - CPR should continue until a veterinary professional takes over, the cat shows clear signs of life, or physical exhaustion prevents further efforts, with a general guideline of at least 20 minutes before considering cessation if there's no response. - Prompt transport to an emergency veterinary hospital is paramount, even while performing CPR, as advanced diagnostics (ECG, blood work, X-rays) and treatments are necessary for survival and addressing the underlying cause. --- If your cat is unconscious and not breathing, start CPR immediately while someone else calls the nearest emergency veterinary hospital. Do not wait to see if your cat improves on its own. Every second without oxygen lowers the chance of survival. If you are alone, perform CPR for two minutes, then call an emergency vet while continuing chest compressions if you can do so hands-free. If your cat has a heartbeat but is not breathing, give rescue breaths only. If your cat has no heartbeat, you will combine chest compressions with rescue breaths. CPR on a cat is physically delicate work. Cats have small, flexible rib cages, and the correct hand position and pressure matter greatly. Press too hard and you can break ribs or damage the liver. Press too softly and you will not move blood. This guide gives you the exact steps, but no written guide replaces hands-on training. If your cat collapses, stops breathing, or has no heartbeat, this is a life-threatening emergency. Do not attempt remote care or video consultation. Transport your cat to an emergency clinic as soon as you have started CPR. ## Is This an Emergency? The table below helps you decide what to do. When in doubt, choose the higher urgency level. A cat that is limp, blue-lipped, or unresponsive is in cardiac arrest, meaning the heart has stopped or is too weak to pump blood. That cat needs CPR and immediate transport. ```figure { "type": "triage", "title": "Urgency triage by severity of signs", "tiers": [ { "tier": "danger", "label": "Go to emergency vet now", "signs": [ "No breathing for more than 10 seconds", "No heartbeat when you press gently on the left side of the chest just behind the elbow", "Unconscious and unresponsive to your voice or touch", "Gums are pale, white, blue, or grey" ], "action": [ "Start CPR right away", "Have someone call the emergency clinic so they are ready", "Continue CPR while transporting" ] }, { "tier": "warn", "label": "Book same-day appointment", "signs": [ "Rapid breathing at rest, more than 40 breaths per minute", "Gums are pale pink or brick red", "Weakness that comes and goes", "Collapse that resolved on its own" ], "action": [ "Call your regular veterinarian today", "Keep your cat quiet and confined to a small space", "Do not feed or give water unless your vet says it is safe" ] }, { "tier": "safe", "label": "Watch at home for a defined period", "signs": [ "Mild lethargy after a known event, such as a vaccination or a stressful car ride, lasting less than 12 hours", "A single episode of vomiting with no other signs, followed by normal eating and energy within 6 hours" ], "action": [ "Monitor closely", "If the cat worsens, develops breathing trouble, or does not improve within the stated time, contact your vet" ] } ] } ``` | Urgency Level | Signs You Can See or Feel | What to Do | |---|---|---| | Go to emergency vet now | No breathing for more than 10 seconds. No heartbeat when you press gently on the left side of the chest just behind the elbow. Unconscious and unresponsive to your voice or touch. Gums are pale, white, blue, or grey. Pupils are wide and do not react to light. Body is limp. | Start CPR right away. Have someone call the emergency clinic so they are ready. Continue CPR while transporting. Do not stop for more than a few seconds at a time. | | Book same-day appointment | Rapid breathing at rest, more than 40 breaths per minute. Gums are pale pink or brick red. Weakness that comes and goes. Collapse that resolved on its own. Coughing, gagging, or open-mouth breathing. | Call your regular veterinarian today. Keep your cat quiet and confined to a small space. Do not feed or give water unless your vet says it is safe. | | Watch at home for a defined period | Mild lethargy after a known event, such as a vaccination or a stressful car ride, lasting less than 12 hours. A single episode of vomiting with no other signs, followed by normal eating and energy within 6 hours. | Monitor closely. If the cat worsens, develops breathing trouble, or does not improve within the stated time, contact your vet. | ## What Is Happening in Cardiac Arrest Cardiac arrest means the heart has stopped pumping effectively. Blood stops moving oxygen to the brain and other organs. Brain cells begin to die within three to four minutes without oxygen. CPR does two things: chest compressions squeeze the heart to push blood, and rescue breaths put oxygen into the lungs. Together they buy time until a veterinarian can deliver advanced care such as oxygen therapy, intravenous fluids, and medications to restart the heart. A cat can go into cardiac arrest for many reasons. Heart disease, severe trauma, choking, poisoning, electric shock, heatstroke, and advanced kidney or respiratory disease can all lead to arrest. Sometimes the cause is never known. Your job during CPR is not to diagnose the cause. Your job is to keep blood and oxygen moving until you reach help. ## How to Check for Breathing and a Heartbeat Place your cat on its right side on a firm, flat surface. A table, the floor, or a hard counter works. Tilt the head back gently to open the airway. Look at the chest and abdomen for movement. Listen near the nose and mouth for breath sounds. Feel for air on your cheek. Check for no more than 10 seconds. To check the heartbeat, place your fingers on the left side of the chest, just behind the elbow where you can feel the ribs. Press gently. You are feeling for a pulse, a rhythmic thump under your fingers. You can also feel for a pulse on the inside of the upper thigh, where the leg meets the body. If you feel nothing in 10 seconds, start compressions. If your cat is breathing but unconscious, do not do CPR. Instead, keep the airway open, keep the cat warm, and transport immediately. If your cat is not breathing but has a heartbeat, give rescue breaths only, at a rate of one breath every 5 seconds. ## Step-by-Step Rescue Breaths Open the airway by tilting the head back slightly. Close the mouth gently with one hand. Place your mouth over the cat's nose. Blow softly and steadily for about one second. Watch the chest rise. If it does not rise, reposition the head and try again. Give one breath every 5 seconds. After every 10 breaths, recheck for a heartbeat. Do not blow hard. A cat's lungs are small, and forceful breaths can rupture them. You want the chest to rise gently, like a slow balloon filling. If the chest does not rise after two attempts, check the mouth for a visible object blocking the airway. Only sweep the mouth if you can see the object. Never push a finger blindly into a cat's throat, as this can push the object deeper. ## Step-by-Step Chest Compressions Place your cat on its right side. Find the point of the elbow on the left front leg. The heart sits just behind that point, near the lower third of the chest. Place the heel of one hand over that spot. For a very small cat, you can use your thumb and forefinger to squeeze the chest from both sides. Press straight down about one-third to one-half the width of the chest. Compress at a rate of 100 to 120 compressions per minute. That is roughly two compressions per second. Let the chest fully recoil between compressions so the heart can refill with blood. After every 30 compressions, give 2 rescue breaths. Continue the cycle of 30 compressions and 2 breaths. If you feel a heartbeat return, stop compressions but continue rescue breaths if the cat is not breathing on its own. Recheck every 2 minutes. Do not stop CPR to transport unless you have a second person who can drive while you continue. If you are alone, carry the cat carefully and continue as best you can, but prioritize getting to the clinic. ## When to Stop CPR Continue CPR until one of these happens: the cat starts breathing on its own and has a heartbeat, a veterinary professional takes over, or you are physically unable to continue. Do not stop after a few minutes because you feel it is hopeless. Cats have survived cardiac arrest with CPR, especially when the arrest happened in front of a witness and CPR began immediately. However, survival depends heavily on the underlying cause and how fast you reach a hospital. Even with perfect CPR, many cats do not survive. That is not your failure. You gave your cat the best possible chance. After any resuscitation attempt, even one that seems successful, your cat must see a veterinarian. Internal injuries, oxygen deprivation, and the original cause of the arrest all require professional evaluation. The [American Veterinary Medical Association](https://www.avma.org/resources-tools/pet-owners) provides general guidance on emergency care and working with your vet. For detailed information on conditions that can lead to cardiac arrest, the [MSD Veterinary Manual](https://www.msdvetmanual.com/pet-owners) offers reliable, owner-friendly explanations. ## What to Do Immediately After CPR If your cat starts breathing again or has a heartbeat, do not stop paying attention. Place the cat on their right side in a quiet, warm area. Keep their head slightly lower than their body if possible. This helps blood flow to the brain. Check every 30 seconds for breathing and a heartbeat. A cat that resumes breathing may stop again. Be ready to restart rescue breaths and compressions if that happens. Wrap the cat in a towel or blanket, but leave the chest and face exposed. Do not use a heating pad. A hot pad can burn a cat that cannot move well. Use your own body heat by holding the wrapped cat close to you. Do not offer food, water, or any medication. The cat may have a damaged airway or a swollen throat. Swallowing could cause choking or aspiration, which means fluid or food entering the lungs. Even if the cat seems fully normal after CPR, they must see a veterinarian immediately. Cardiac arrest is a symptom, not a disease. The underlying cause is still present and can stop the heart again. ## What to Write Down Before You Call or Arrive When you contact a veterinary clinic, they will ask specific questions. Having answers ready saves time. Write these down while you travel or wait: | Information | What to record | | --- | --- | | Time of collapse | Exact time you found the cat unresponsive | | Time CPR started | When you began rescue breaths or compressions | | Number of breaths and compressions | Rough count is fine, for example 30 breaths and 200 compressions | | Any response | Coughing, gasping, limb movement, eye blinking | | Gum color | Pink, pale, white, blue, or gray | | Known health conditions | Heart disease, kidney disease, diabetes, seizures | | Medications | Names and last dose times of any prescription drugs | | Possible exposures | Toxins, trauma, choking hazards, recent travel | Do not spend time searching for this information if the cat is still in arrest. CPR comes first. If someone else is present, have them gather details while you continue compressions. ## What Not to Do at Home Do not give your cat any human medication, including aspirin, ibuprofen, or acetaminophen. These drugs are toxic to cats and can cause liver failure or bleeding. Dosing must come from the treating veterinarian because cat metabolism differs sharply from human metabolism. Do not perform the Heimlich maneuver on a cat that is not choking. If you suspect a blocked airway, open the mouth and look. Only sweep out an object you can clearly see. Blind finger sweeps can push the object deeper. Do not shake the cat, slap the chest, or apply ice water. These old methods do not restart a heart and can cause additional injury. Do not attempt CPR on a cat that is breathing normally and has a heartbeat. Chest compressions on a beating heart can cause rib fractures or lung damage. Do not delay transport to a clinic while you search online or call a telehealth service. Remote care cannot examine, listen to, or treat a cat in cardiac arrest. Hands-on emergency care is required, and every minute without it reduces the chance of recovery. ## What Happens at the Veterinary Hospital The emergency team will take over immediately. They will place an intravenous catheter, which is a small tube in a vein, to give fluids and medications directly into the bloodstream. They will likely give oxygen and may place a breathing tube. The veterinarian will ask you the questions listed above. They will also ask about the cat's age, vaccination status, and any recent changes in behavior, appetite, or energy. Common tests include: - Blood work to check organ function, electrolytes, and blood sugar - An electrocardiogram, or ECG, to measure the heart's electrical activity - Chest X-rays to look for fluid, masses, or heart enlargement - Blood pressure measurement - Ultrasound of the chest or abdomen The cost of these tests varies widely by region and clinic. A basic emergency visit with blood work and X-rays might range from several hundred to over a thousand dollars. Advanced imaging or overnight intensive care can cost more. Ask the clinic for a written estimate before they proceed with non-emergency tests. In a true emergency, they will stabilize the cat first and discuss costs after. The veterinarian may diagnose a condition such as hypertrophic cardiomyopathy, which is a thickened heart muscle, or an arrhythmia, which is an irregular heartbeat. Other causes include toxins, severe infection, trauma, or kidney failure. Some cats have no identifiable cause despite full testing. ## Aftercare and Recovery at Home If the cat survives, recovery depends on the underlying cause and how quickly CPR began. Some cats return home within a day. Others need several days in the hospital. At home, you will likely need to give medications on a strict schedule. Heart medications, anti-arrhythmic drugs, or fluids under the skin are common. The veterinarian will show you how to give each one. Do not adjust doses on your own. Limit activity. Keep the cat in a single quiet room with easy access to food, water, and a litter box. Do not allow jumping, running, or playing for at least one to two weeks, or longer if the veterinarian advises. Watch for these warning signs and call the clinic immediately if they appear: - Difficulty breathing or rapid breathing at rest - Pale or blue gums - Collapse or weakness - Seizures - Refusing to eat for more than 24 hours - Vomiting or diarrhea Follow-up visits are essential. The veterinarian will repeat blood work, imaging, or an ECG to monitor the condition. Prognosis varies widely. Some cats live for years after successful CPR. Others have a guarded outlook, especially if the heart stopped for several minutes before compressions began. ## When to Stop CPR and Let Go You cannot perform CPR forever. Physical exhaustion is real, and a cat that has not responded after 20 minutes of continuous, correct CPR has a very low chance of survival. The veterinarian will guide you on when to stop if you are at a clinic. At home, stop CPR if: - The cat shows clear signs of life, such as breathing, a heartbeat, or movement - You are physically unable to continue - More than 20 minutes have passed with no response - A veterinarian tells you to stop If you stop and the cat has not revived, they have passed. Grief is natural. You did not cause the cardiac arrest, and you gave your cat the best chance by acting immediately. Many owners find comfort in knowing they tried. Some clinics offer paw prints or fur clippings as keepsakes. Ask if that is something you want. The decision to stop is difficult. There is no shame in stopping early if you are exhausted, and no shame in continuing until a professional takes over. Your effort matters. ## Common Mistakes Owners Make and What to Do Instead When panic sets in, even well-meaning owners can make errors that reduce the chance of success. Knowing these mistakes before an emergency helps you act correctly under pressure. **Mistake: Compressing too fast or too slow.** Owners often rush compressions out of fear. Aim for 100 to 120 compressions per minute. That feels slower than you think. Count aloud or hum a steady beat. If you have a song in your head that matches that tempo, use it. **Mistake: Pushing on the wrong spot.** The heart sits lower and further back than many people expect. Place your hand directly over the chest where the elbows meet the body when the cat is lying on its side. Pushing too far forward on the ribcage does little to move blood. **Mistake: Stopping compressions to check for a pulse.** Every time you pause, blood flow stops completely. Check for a pulse only every two minutes, and keep the pause under ten seconds. If you are not sure you feel a pulse, continue compressions anyway. **Mistake: Giving breaths and compressions in the wrong order.** For a cat in cardiac arrest, start with two rescue breaths, then immediately begin chest compressions. Do not spend time trying to find a heartbeat before starting. The heart may still be beating weakly, and compressions will help it. **Mistake: Giving up too early.** Effective CPR can take several minutes before signs of life return. If you are alone, continue until a veterinarian or emergency team takes over, or until you are physically unable to continue. Fatigue is a valid reason to stop, but frustration is not. **Mistake: Tilting the head too far back.** Cats have delicate necks. Overextending the airway can actually block it. Tilt the head only slightly, just enough to open the mouth and see the throat clearly. | Common Mistake | Better Action | | --- | --- | | Compressing too fast | Count 100 to 120 beats per minute aloud | | Pushing on the upper ribcage | Place hand where elbows meet the chest | | Stopping to check pulse often | Check only every two minutes, pause under 10 seconds | | Tilting head too far back | Tilt slightly, just enough to open the airway | | Giving up after one minute | Continue until a professional takes over or you cannot continue | ## How to Reduce the Chance of It Happening Again CPR treats the result of cardiac arrest, not the cause. The underlying problem is often heart disease, trauma, poisoning, or a severe respiratory issue. You cannot prevent every emergency, but you can lower the odds. Schedule regular veterinary checkups at least once a year, and twice a year for senior cats. Your veterinarian can listen for heart murmurs or irregular rhythms that may not show outward signs. The American Veterinary Medical Association offers guidance on preventive care and what to expect during a routine visit. Cats hide illness remarkably well, so a normal appearance does not mean a healthy heart. Keep toxic substances out of reach. Lilies, antifreeze, human medications, and certain houseplants can cause sudden cardiac collapse. Know which plants you own and remove any that are dangerous. Store all medications in closed cabinets, never on counters where a cat can knock them down. Maintain a healthy weight. Obesity strains the heart and increases the risk of respiratory problems. Ask your veterinarian for a feeding plan if your cat is overweight. Sudden weight loss is also a concern, so track changes at home. Reduce stress where possible. Cats thrive on routine. Major changes like moving, new pets, or loud construction can trigger hidden heart conditions. Provide quiet hiding spaces and keep feeding times consistent. Learn your cat's normal resting breathing rate. Count breaths per minute when the cat is asleep. A healthy adult cat typically breathes 15 to 30 times per minute. If you notice the rate climbing at rest, or if your cat breathes with an open mouth, seek veterinary care promptly. These signs can indicate heart failure, which is a leading cause of cardiac arrest. ## What Recovery and Ongoing Management Usually Look Like If your cat survives cardiac arrest, the recovery path depends entirely on what caused the arrest and how long the brain went without oxygen. There is no single timeline. Immediately after resuscitation, your cat will stay in the veterinary hospital, often in intensive care. The team will monitor heart rhythm, blood pressure, oxygen levels, and brain function. Many cats need oxygen therapy and intravenous fluids. Some need medications to support blood pressure or heart rhythm. The first 24 to 72 hours are the most critical. If the cause was a reversible problem like a temporary blockage or a medication reaction, recovery can be surprisingly quick. Some cats go home within a few days. If the cause was severe heart disease or cancer, the outlook is more guarded. Your veterinarian will discuss options honestly. At home, recovery often involves rest in a quiet room, a strict medication schedule, and reduced activity. You may need to confine your cat to a single room for a week or more. Follow-up visits are common at one week, one month, and then every few months. Blood tests and heart imaging may be repeated. Full recovery of normal energy and behavior can take two to four weeks. Some cats return to their old selves completely. Others have lasting neurological effects, such as wobbliness, vision changes, or altered behavior. Your veterinarian will guide you on what to expect for your specific cat. Ongoing management means watching for warning signs daily. Track breathing rate, appetite, and energy. Report any decline immediately. Many cats with heart disease live comfortably for months or years with medication and monitoring. The American Animal Hospital Association provides resources on managing chronic conditions and working with your veterinary team. ## Frequently Asked Questions **Can I hurt my cat by doing CPR wrong?** Yes, it is possible to injure a cat during CPR. Rib fractures and bruising can occur, especially in small or elderly cats. However, a cat in cardiac arrest is already dying. The risk of injury from CPR is far less than the certainty of death without it. Focus on correct hand placement and steady compressions. If you break a rib, that is painful but survivable. Cardiac arrest without intervention is not. **How do I know if my cat is actually in cardiac arrest versus just unconscious?** Check for breathing and response first. Call the cat's name, gently tap the paw, and watch the chest for movement. If the cat is unconscious and not breathing, start CPR immediately. Do not spend time trying to find a pulse. A cat that is unconscious but still breathing needs emergency care but should not receive chest compressions. When in doubt, start rescue breaths and reassess. **Should I do CPR on a cat that is still breathing but very weak?** No. CPR is only for cardiac arrest, meaning the heart has stopped and the cat is not breathing. Compressing the chest of a cat that is still breathing can cause serious injury. If the cat is weak but breathing, keep it warm, keep it calm, and transport it to an emergency veterinarian immediately. Do not delay transport to attempt any home treatments. **How long should I keep doing CPR before giving up?** Continue until a veterinary professional takes over, until you are physically exhausted, or until you have performed CPR for at least 20 minutes without any response. Some cats respond after several minutes of good CPR. If you are alone and exhausted, that is a valid reason to stop. You did everything you could. There is no shame in stopping when your body cannot continue. **My cat has heart disease. Should I learn CPR before an emergency happens?** Yes, absolutely. Cats with known heart disease are at higher risk of cardiac arrest. Ask your veterinarian to demonstrate proper technique on a model during your next visit. Practice the hand placement and rhythm at home so it becomes automatic. Also keep your veterinarian's emergency number and the nearest 24-hour hospital's address in your phone and on your fridge. **What should I do after I stop CPR and my cat has not revived?** If you have stopped because you are exhausted or because a professional has taken over, the next step is to let the veterinary team guide you. They may continue resuscitation efforts or discuss whether to stop. If you are at home and have stopped, contact your veterinarian for guidance on next steps, including aftercare. Do not blame yourself. You acted in a crisis with the knowledge you had. ## Related Clinical & Scientific Guides * [Dog Heatstroke: Emergency Cooling Steps and When to Rush](/knowledge/veterinary-medicine/online-vet-and-care-costs/dog-heatstroke-emergency-cooling-steps-when-to-rush) * [Dog Vomiting: When to Call the Vet and What to Do at Home](/knowledge/veterinary-medicine/online-vet-and-care-costs/dog-vomiting-when-to-call-vet) * [How to Make a Dog Vomit Safely at Home: When and How](/knowledge/veterinary-medicine/online-vet-and-care-costs/make-dog-vomit-safely) ## References and Further Reading - [AVMA Telehealth and Veterinary Telemedicine](https://www.avma.org/resources-tools/animal-health-and-welfare/telehealth-telemedicine-veterinary-practice) - [FDA Veterinary Telemedicine Information](https://www.fda.gov/animal-veterinary/resources-you/telemedicine-veterinary-medicine) - [AVMA Pet Owner Resources](https://www.avma.org/resources-tools/pet-owners) - [MSD Veterinary Manual Pet Owner Version](https://www.msdvetmanual.com/pet-owners) - [AAHA Pet Owner Resources](https://www.aaha.org/for-pet-parents/) ## Related Articles - [How to Perform CPR on a Dog: Step-by-Step Guide](/knowledge/veterinary-medicine/online-vet-and-care-costs/how-to-perform-cpr-on-a-dog-step-by-step-guide) - [Cat Constipation: When to Worry and How to Help](/knowledge/veterinary-medicine/online-vet-and-care-costs/cat-constipation-when-to-worry) - [Cat Limping: When to Worry and What to Do](/knowledge/veterinary-medicine/online-vet-and-care-costs/cat-limping-when-to-worry) - [Cat Sneezing: When to Worry and How to Help](/knowledge/veterinary-medicine/online-vet-and-care-costs/cat-sneezing-when-to-worry) - [Cat Vomiting: When to Worry and How to Help](/knowledge/veterinary-medicine/online-vet-and-care-costs/cat-vomiting-when-to-worry) > This article is general educational information for pet owners.
