# Guinea Pig Not Moving: Causes and Emergency Care A guinea pig that stops moving is almost always seriously ill, and this is a medical emergency. Guinea pigs are prey animals that hide weakness until they can no longer do so, so a guinea pig not moving often means the problem has been building for hours or days. Call an exotic or small animal veterinarian right away. This article is educational and is not a substitute for veterinary diagnosis or treatment. ## Quick Answer - Treat a guinea pig that will not move as an emergency and call an exotic vet immediately, even if it is late at night. - Keep the guinea pig warm, quiet, and upright, and do not force food or water into its mouth. - Check for breathing effort, drooling, bloating, and droppings so you can report what you see. - Do not wait to see if it improves on its own. Guinea pigs that stop moving can decline within hours. - Bring the guinea pig in a small carrier with a towel and a heat source, and bring a cagemate if it has one. ## What "Not Moving" Looks Like and What Is Normal A healthy guinea pig is active in bursts. It eats hay throughout the day, runs to the food bowl, popcorns, and reacts when you open the cage. Normal guinea pigs also rest a lot, often stretched out or flopped on their side. Resting is not the same as not moving. A guinea pig that is not moving may sit hunched in a corner, stay in one spot for hours, or lie flat and not lift its head. It may not respond when you touch it or offer food. Some guinea pigs become wobbly, tilt their head, or have trouble using their back legs. Others simply freeze and stop reacting to anything. Owners often describe this as a guinea pig sick not moving, and that is exactly what is happening. A guinea pig that is not eating or drinking or moving is in a critical state. Guinea pigs need constant food moving through their gut, and when they stop eating, the whole system starts to shut down. ## Why Is My Guinea Pig Not Moving? Main Causes Many different problems can cause a guinea pig to stop moving. The table below lists the most common ones and how urgent each is. | Cause | Typical clues | How urgent | |---|---|---| | GI stasis (gut slowdown) | Not eating, small or no droppings, hunched posture, bloated belly | Emergency now | | Dental disease (malocclusion) | Drooling, weight loss, dropping food, mouth bleeding, nasal or eye discharge | Urgent, same day | | Hypothermia (low body temperature) | Cold to the touch, limp, unresponsive, often after illness or a cold room | Emergency now | | Respiratory infection | Labored breathing, clicking or rattling sounds, discharge from nose or eyes | Emergency now | | Pain from any source | Grinding teeth, squinting, hunched back, reluctance to move | Urgent, same day | | Neurological problem | Head tilt, circling, rolling, seizures, weakness in the legs | Emergency now | | Intestinal obstruction | Painful defecation, a firm mass in the belly, rolling episodes | Emergency now | | Cancer or organ disease | Weight loss, enlarged lymph nodes, gradual decline, older age | Urgent, same day | ### GI Stasis and Gut Problems Gastrointestinal stasis is one of the most common reasons a guinea pig stops moving. The gut slows or stops, gas builds up, and the guinea pig becomes painful and weak. Non-obstructive stasis is common in guinea pigs, while a true blockage is less common but far more dangerous [1]. A guinea pig with a blockage may have a firm, painful belly and may roll or cry out. If your guinea pig has not produced droppings in 12 hours or more, treat it as an emergency. Our guide to [Guinea Pig Care: GI Stasis Emergency Triage & Massage Protocol](/knowledge/veterinary-medicine/exotic-small-animals/guinea-pig-care-gi-stasis-emergency-triage-massage-protocol) walks through what to do while you arrange transport. ### Dental Disease Dental problems are common in guinea pigs because their teeth grow continuously. Malocclusion, where the upper and lower teeth do not line up, causes overgrowth, sharp edges, pain while chewing, and trouble eating [2]. Causes include genetics, not enough hay to chew, and vitamin C deficiency [2]. Dental disease can lead to drooling, weight loss, mouth bleeding, tooth root abscesses, and discharge from the nose or eyes [2]. A guinea pig in mouth pain may stop eating, then stop moving. See our article on [Guinea Pig Care: Dental disease malocclusion and assisted feeding](/knowledge/veterinary-medicine/exotic-small-animals/guinea-pig-care-dental-disease-malocclusion-and-assisted-feeding) for more detail. ### Hypothermia Guinea pigs handle cold poorly. A guinea pig that has been sick, wet, or kept in a cold room can drop its body temperature and become limp and unresponsive. In one reported case, a guinea pig with a serious intestinal problem arrived mildly hypothermic [1]. Warming a cold guinea pig slowly is part of first aid, but it does not replace veterinary care. ### Respiratory and Other Infections Respiratory infections can make a guinea pig too weak to move and too short of breath to eat. Bacterial infections can also spread from the mouth or skin into the lymph nodes, causing swelling that may appear on one side of the neck [3]. Infection can then spread to the ears, sinuses, or eyes [3]. Learn the early signs in [Guinea Pig Respiratory Infections: Causes, Signs, and Treatment](/knowledge/veterinary-medicine/small-mammal-care/guinea-pig-respiratory-infections-causes-signs-treatment). ### Neurological Issues Head tilt, circling, rolling, and seizures point to a neurological problem. These can come from ear infections, toxins, trauma, or other disease. A guinea pig with these signs needs immediate veterinary assessment. ### Pain, Cancer, and Organ Disease Pain from any cause can make a guinea pig stop moving. Pain assessment in guinea pigs is still limited, and many pain scales used in other species have not been developed for guinea pigs [4]. This means owners and vets must rely on behavior and physical exam findings. Cancer is uncommon in young guinea pigs but becomes more common after age 4 to 5, and lymphosarcoma is a malignant cancer that can enlarge the lymph nodes, liver, or spleen with a poor prognosis [3]. ## Red Flags That Make It an Emergency Go to an emergency clinic now if your guinea pig has any of these signs: - Not moving at all, or limp and unresponsive - Labored breathing, open-mouth breathing, or a clicking sound - No droppings for 12 hours or more - A hard, swollen, or painful belly - Drooling or food falling out of the mouth - Cold to the touch - Head tilt, rolling, or seizures - Bleeding from the mouth or rectum - Collapse or inability to stand Do not wait for a morning appointment if you see these signs. Guinea pigs can go from weak to critical in a short time. ## Safe Things You Can Do at Home While Waiting Your job is to keep the guinea pig stable and get to a vet. Do not try to treat the problem yourself. - Keep it warm. Use a wrapped heat pack or a warm water bottle under half the carrier so the guinea pig can move away if it gets too hot. Never put a guinea pig directly on a heat source. - Keep it quiet. Reduce noise and handling. Stress makes a sick guinea pig worse. - Do not force food or water into the mouth. A guinea pig that cannot swallow can choke or inhale fluid. Assisted feeding is only safe when a vet has shown you how and the guinea pig is stable. - Do not give human medications. Never give aspirin, ibuprofen, or acetaminophen. Doses for guinea pigs are not well established, and many common drugs are toxic to them. - Do not make it vomit. Guinea pigs cannot vomit, and trying to force this can cause serious harm. - Note the details. Write down when it last ate, last produced droppings, and what the droppings looked like. Bring this to the vet. - Bring a cagemate. Guinea pigs are social, and a companion can reduce stress during the visit. If you suspect gut stasis, gentle abdominal massage may help while you wait, but only if the belly is soft and the guinea pig is not crying out in pain. Stop at once if it seems painful. ## What the Veterinarian Will Check and Test Your vet will start with a full physical exam. They will check the heart and lungs, feel the belly for gas or masses, look at the teeth, and take the body temperature. They will also weigh your guinea pig, since weight loss is a major clue. Common tests include: - Skull x-rays to assess the teeth, since back molars often cause problems even when the front teeth look normal [2] - Abdominal x-rays or ultrasound to look for gas, blockage, or masses - Blood work to check organ function and infection - Fecal testing if parasites or digestive issues are suspected Treatment depends on the cause. Dental disease may need trimming or filing, and chronic cases may need repeated trims every month [2]. Severe lymph node infections may need surgery to remove the nodes [3]. Pain medication is often part of care, but doses for guinea pigs are often extrapolated from other species because validated values are limited [4]. Your veterinarian will calculate any dose from your pet's weight and health. ## Prevention and Daily Monitoring Most guinea pig emergencies are easier to prevent than to treat. Small daily habits catch problems early. - Weigh your guinea pig weekly. A drop of even a few ounces matters. - Check droppings daily. Fewer, smaller, or misshapen droppings are an early warning. - Feed unlimited grass hay. Hay keeps the teeth worn down and the gut moving [2]. - Provide a constant source of vitamin C. Guinea pigs cannot make their own, and deficiency contributes to dental disease [2]. - Watch for drooling. Drooling or dropping food means a vet visit soon [2]. - Keep the cage clean and dry. Dirty bedding and rough surfaces can cause skin wounds that lead to infection [3]. - Isolate sick guinea pigs. Infection spreads between guinea pigs through bites, wounds, sneezing, coughing, and sexual contact [3]. - Keep the room temperature steady. Avoid drafts and cold floors. - Provide a companion. Guinea pigs housed alone often have problems related to aging, dental disease, and poor care [2].

Only a veterinarian who examines your pet can do that. Contact a veterinarian the same day if your guinea pig is eating less, has lost weight, is drooling, or has changed its droppings. Go to an emergency clinic now if your guinea pig is not moving, is struggling to breathe, has a bloated belly, has not passed droppings in 12 hours, is cold to the touch, or is having seizures or rolling episodes. Schedule a routine visit if you notice gradual changes like mild weight loss, occasional drooling, or reduced activity over several days. If you are unsure how serious the situation is, call an exotic vet and describe what you see. It is always better to call and be told to wait than to delay care for a guinea pig that is crashing. ## Frequently Asked Questions ### Should I wait to see if my guinea pig starts moving again? No. A guinea pig that stops moving is usually in a serious medical crisis, and waiting can cost you precious time. Call an exotic vet right away and describe the signs you are seeing. ### Can I give my guinea pig food or water by syringe at home? Only if a veterinarian has shown you how and your guinea pig is stable enough to swallow. A weak guinea pig can choke or inhale liquid into its lungs. Never force anything into the mouth of a guinea pig that is limp or unresponsive. ### Is a guinea pig that is not moving but still breathing okay to monitor at home? No. Breathing alone does not mean the guinea pig is stable. Labored breathing, a cold body, or a bloated belly are all signs that need emergency care. Get veterinary help immediately. ### What if my guinea pig is not eating and barely moving but still nibbles a little? Even a small amount of nibbling does not rule out a serious problem. A guinea pig that is barely moving and eating very little is likely in gut stasis or another crisis. See a vet the same day. ### Can I use human pain medicine for my guinea pig? No. Never give human pain relievers to a guinea pig. Doses for guinea pigs are not well established, and some common drugs are toxic. Pain medication must come from your veterinarian, who will set the dose based on your pet's weight and health. ## Related Articles - [Guinea Pig Care: GI Stasis Emergency Triage & Massage Protocol](/knowledge/veterinary-medicine/exotic-small-animals/guinea-pig-care-gi-stasis-emergency-triage-massage-protocol) - [Guinea Pig Respiratory Infections: Causes, Signs, and Treatment](/knowledge/veterinary-medicine/small-mammal-care/guinea-pig-respiratory-infections-causes-signs-treatment) - [Complete Guinea Pig Care Guide](/knowledge/veterinary-medicine/small-mammal-care/guinea-pig-care) - [Guinea Pig Care: Dental disease malocclusion and assisted feeding](/knowledge/veterinary-medicine/exotic-small-animals/guinea-pig-care-dental-disease-malocclusion-and-assisted-feeding) - [Guinea Pig Health: Common Conditions and Prevention](/knowledge/veterinary-medicine/small-mammal-care/guinea-pig-health-common-conditions-and-prevention) - [Guinea Pig Care: Respiratory Infection Symptoms & Antibiotic Protocol](/knowledge/veterinary-medicine/exotic-small-animals/guinea-pig-care-respiratory-infection-symptoms-antibiotic-protocol) - [Guinea Pig Not Moving but Breathing: What to Do](/knowledge/veterinary-medicine/small-mammal-care/guinea-pig-not-moving-but-breathing) - [Guinea Pig Not Using Back Legs: Causes and Urgency](/knowledge/veterinary-medicine/small-mammal-care/guinea-pig-not-using-back-legs) - [Guinea Pig Not Eating or Drinking: What to Do](/knowledge/veterinary-medicine/small-mammal-care/guinea-pig-not-eating-or-drinking) ## References 1.
