# Cat Dehydration: Safe Liquids and Electrolytes at Home What can I give my cat for dehydration? For most mildly dehydrated cats, the safest answer is plain fresh water, plus moisture-rich wet food or a little unsalted broth. Oral electrolyte solutions made for pets can help in some cases, but they are not a substitute for veterinary fluids when dehydration is moderate or severe. This article is educational and is not a substitute for veterinary diagnosis or treatment. ## Quick Answer - Fresh, clean water in several bowls is the first and safest choice for a dehydrated cat. - Wet food, lickable treats, and unsalted meat broth add water without forcing your cat to drink. - Do not give human sports drinks, energy drinks, milk, or sugary liquids. They can cause stomach upset and electrolyte problems. - Plain unflavored pediatric electrolyte solution may be offered in small amounts only if your veterinarian approves it for your cat. - A cat who is weak, vomiting, not eating, or has tacky gums needs a veterinarian the same day, not home remedies. ## How to Help a Cat Hydrate at Home Start by figuring out how dehydrated your cat really is. You can check skin elasticity, gum moisture, and gum color at home. A simple technique is described in [How to Check Your Cat's Hydration at Home](/knowledge/veterinary-medicine/vet-visit-decisions/how-to-check-your-cats-hydration-at-home). If the skin over the shoulders stays tented, the gums feel sticky, or the gums look pale or blue, stop home care and call your vet. ### Step 1: Offer Water in More Than One Place Cats often drink more when water is easy to find and appealing. Put out multiple bowls in quiet spots away from the litter box and food. Some cats prefer a wide ceramic bowl, some prefer a fountain, and some prefer a glass of water on the counter. Refresh the water at least twice a day. A cat on dry food may not drink enough to stay well hydrated. Research shows cats fed dry diets tend to have lower total water intake, and adding high-moisture treats or food can raise it [1]. A scoping review of 32 studies found healthy cats consumed roughly 23 to 51 mL of total water per kilogram of body weight per day, though individual needs vary [2]. ### Step 2: Add Water to Food Wet food is the easiest way to get more water into a cat who will not drink. You can also add a spoonful of warm water to canned food, or offer a lickable treat with high moisture. A study of healthy cats on dry diets found that high-moisture lickable treats containing amino acids and sodium increased total water intake and lowered urine specific gravity, which is a marker of hydration [1]. If your cat is vomiting, do not push food. Withhold food for at least 12 hours if the stomach or intestines seem inflamed, but keep fresh water available [3]. After 12 hours, offer a small amount of bland food such as canned tuna packed in water [3]. If vomiting continues, your cat refuses food, or your cat seems lethargic, go to a veterinary clinic right away [3]. ### Step 3: Try Unsalted Broth Plain, unsalted chicken or beef broth can make water more tempting. Warm it slightly, then offer a few tablespoons in a bowl or mix it into wet food. Check the label. Many broths contain onion, garlic, or added salt, and those are not safe for cats. If you cannot find a broth with no onion, no garlic, and no added salt, skip it. ### Step 4: Consider Oral Rehydration Only With Veterinary Guidance Oral rehydration solutions are designed to replace water and electrolytes. Some are made for pets, and some are made for human infants. The right product and the right amount depend on your cat's weight, health conditions, and how dehydrated your cat is. Your veterinarian calculates the dose from your pet's weight and health, so ask before you give anything. Never use a human sports drink as a substitute. The sugar and electrolyte balance is wrong for cats, and the high sugar can worsen diarrhea. Do not give milk either. Many adult cats cannot digest lactose well, and milk can cause vomiting or diarrhea that makes dehydration worse. ### Step 5: Know When Home Care Is Not Enough Fluids are drugs. They can help or harm depending on the type, route, and rate [4]. A veterinarian designs a fluid plan after assessing your cat, and that plan may change during treatment based on how your cat responds [4]. Kittens and very young cats have different fluid and electrolyte needs than adults, and they can dehydrate faster [5]. If your cat is a kitten, is elderly, or has kidney disease, diabetes, or heart disease, call your vet early instead of waiting. ## What Can I Give My Cat for Electrolytes? The short answer is that most mildly dehydrated cats do not need a separate electrolyte product. They need water and moisture-rich food. Electrolyte solutions matter more when a cat has been vomiting, has diarrhea, or has been losing fluids for a while. If your veterinarian recommends an oral electrolyte solution, use only the product and amount your vet specifies. Do not mix your own salt and sugar water at home. The balance of sodium, potassium, and other minerals is hard to get right, and a homemade mix can make things worse. For cats who need more than oral fluids, a veterinarian may prescribe subcutaneous fluids, which are given under the skin at home. The technique is covered in [How to Give Your Cat Subcutaneous Fluid Injections at Home](/knowledge/veterinary-medicine/senior-and-chronic-care/give-cat-subcutaneous-fluids-home). This is a veterinary treatment, not a home remedy, and it should only be done with a prescription and training from your vet. ## Daily Hydration Checklist | Task | How Often | Why It Matters | |---|---|---| | Refresh water bowls | At least twice daily | Cats often refuse stale water | | Offer wet food or added water | Once or twice daily | Food provides most of a cat's water intake | | Check gums and skin turgor | Once daily when you are worried | Early signs are easier to treat | | Track litter box output | Daily | Less urine can signal dehydration | | Weigh your cat if possible | Weekly | Weight loss can point to ongoing fluid loss | | Offer unsalted broth | As a treat, not a meal | Adds water and encourages drinking | ## Signs That Something Is Wrong Mild dehydration can look like a cat who drinks more, has slightly tacky gums, or has less elastic skin. More serious signs include sunken eyes, weakness, wobbling, cold paws, fast breathing, and a cat who will not eat or drink at all. A full list is in [Cat Dehydration Symptoms: How to Tell and What to Do](/knowledge/veterinary-medicine/digestive-and-urinary-care/cat-dehydration-symptoms-how-to-tell). Vomiting and diarrhea are common causes of dehydration in cats. If your cat vomits more than once or twice, or has diarrhea for more than a day, call your vet. If your cat is diabetic and vomits, call your veterinarian to decide the best course of action before you change anything at home [3]. Watch for these red flags: - Gums that feel dry or sticky - Skin that stays tented after you gently pinch it - Panting or open-mouth breathing - Not urinating for 12 hours or more - Vomiting that will not stop - Refusing all food and water - Acting confused, wobbly, or very quiet ## Common Mistakes Owners Make **Giving human sports drinks.** These are made for people, not cats. The sugar and sodium levels do not match a cat's needs, and they can cause stomach upset. **Giving milk.** Many cats are lactose intolerant, and milk can trigger diarrhea that makes dehydration worse. **Forcing water with a syringe.** A cat who is forced to swallow can inhale liquid into the lungs. If your cat will not drink, that is a reason to call your vet, not to force fluids. **Using human medications without veterinary advice.** Over-the-counter human medications are not dosed for your cat's medical history, other medications, or breed sensitivities [6]. Some can hide signs of a more serious problem, and by giving them you may miss clues that something else is going on [6]. **Waiting too long.** Cats hide illness well. By the time a cat looks weak, dehydration may already be moderate or severe. Early calls to your vet are cheaper and safer than emergency visits. **Skipping the phone call.** Emergency care often starts with a phone call to your veterinarian. Be ready to describe what happened, and follow any first aid or transport instructions you are given [7]. Calling ahead also lets the clinic prepare for your arrival [7]. ## Supplies and Setup That Matter A few simple items make home hydration easier and safer. - Several water bowls, including one wide shallow bowl and one fountain if your cat likes moving water - Canned wet food or high-moisture lickable treats - Unsalted broth with no onion or garlic - A kitchen scale for tracking your cat's weight - A notebook or phone app for tracking water intake, urine, and vomiting - A pet carrier that is easy to load, in case you need to travel to the vet If your cat needs liquid medication, some cats accept it better without a syringe. Tips are in [How to Give Your Cat Liquid Medicine Without a Syringe: Alternative Methods](/knowledge/veterinary-medicine/pet-medication-guide/give-cat-liquid-medicine-without-syringe). Never mix medication into a full bowl of water, because you cannot tell how much your cat actually drank. ## Limitations and When to Contact a Veterinarian Home care works best for mild dehydration in a cat who is otherwise bright, eating, and not vomiting. It is not a treatment for shock, severe fluid loss, or electrolyte imbalances. Those need veterinary fluids, blood work, and monitoring. Every cat is different, and your veterinarian is the only person who can judge your cat's specific case. Call your veterinarian the same day if your cat: - Has been vomiting or having diarrhea for more than 24 hours - Is refusing food but still drinking - Has tacky gums or mild skin tenting - Is a kitten, senior, or has a chronic condition like kidney disease or diabetes - Has been drinking much more or much less than usual for more than a day Go to an emergency clinic now if your cat: - Is weak, wobbly, or cannot stand - Has pale, white, or blue gums - Is breathing fast or with an open mouth - Has collapsed or is unresponsive - Has not urinated for 12 hours or more - Is vomiting repeatedly and cannot keep water down If you think your cat ate something toxic, call the Pet Poison Helpline or the ASPCA Animal Poison Control Center right away. Have the product name and your cat's weight ready. ## Frequently Asked Questions ### Can I give my cat Pedialyte? Plain unflavored pediatric electrolyte solution may be an option for some cats, but only with your veterinarian's approval. The amount depends on your cat's weight and health, so your vet sets the dose. Never use a flavored version or a human sports drink. ### How much water should my cat drink each day? Healthy cats in research studies consumed about 23 to 51 mL of total water per kilogram of body weight daily, counting water from food [2]. Individual needs vary with diet, activity, and health. A cat on dry food often drinks more from the bowl but still takes in less total water than a cat on wet food. ### Is tuna water safe for a dehydrated cat? Canned tuna packed in water is sometimes used as a bland food for cats who have been vomiting [3]. The water from the can can be offered in small amounts, but check that the can does not contain added salt or flavorings. It is a short-term trick, not a daily hydration plan. ### Can I give my cat chicken broth? Yes, if the broth is unsalted and contains no onion, onion powder, or garlic. Those ingredients are toxic to cats. Warm the broth slightly and offer a few tablespoons, or mix it into wet food. ### Will wet food alone hydrate my cat? Wet food helps a lot because it is mostly water, and high-moisture foods and treats can raise total water intake in cats on dry diets [1]. It is not a full replacement for veterinary fluids if your cat is already moderately or severely dehydrated. If your cat is weak or not eating, call your vet. ## Related Articles - [How to Check Your Cat's Hydration at Home](/knowledge/veterinary-medicine/vet-visit-decisions/how-to-check-your-cats-hydration-at-home) - [Cat Dehydration Symptoms: How to Tell and What to Do](/knowledge/veterinary-medicine/digestive-and-urinary-care/cat-dehydration-symptoms-how-to-tell) - [How to Give Your Cat Subcutaneous Fluid Injections at Home](/knowledge/veterinary-medicine/senior-and-chronic-care/give-cat-subcutaneous-fluids-home) - [How to Give Your Cat Liquid Medicine Without a Syringe: Alternative Methods](/knowledge/veterinary-medicine/pet-medication-guide/give-cat-liquid-medicine-without-syringe) - [How to Safely Give Your Dog or Cat a Bath at Home](/knowledge/veterinary-medicine/senior-and-chronic-care/safe-bathing-dog-cat-home) - [Cat Vomiting and Not Drinking Water: Hydration Tips and Red Flags](/knowledge/veterinary-medicine/digestive-and-urinary-care/cat-vomiting-not-drinking-water) - [Is Tap, Distilled, or Bottled Water Safe for Cats?](/knowledge/veterinary-medicine/nutrition/safe-water-for-cats-tap-distilled-bottled) - [What Medicine Can I Give My Cat?
