Why do cats hide when they are sick?

Cats are masters at hiding. They can squeeze themselves into tiny spaces, lie silently for hours, and make themselves almost invisible. While any cat will hide at times, if your cat starts hiding more than normal and changes his behavior, it could indicate that he’s sick. Many cats will hide when they’re sick and avoid the other members of their family, including you. If your cat starts hiding excessively and you suspect he’s sick, it’s important to be able to recognize that he needs help and get him right to the vet. While it might seem odd that a cat in need of help would hide from you, there’s actually a logical reason behind this behavior. So, why do cats hide?

Why do cats hide when they are sick?

If your cat’s not feeling his best, you might notice that he hides under the bed or in a closet; if he’s an outdoor cat, he might wander away and seek out a place where he can be alone.

This behavior is caused by your cat’s natural instincts. In the wild, cats seek out a secluded space to protect themselves when they’re sick. Cats know that when they’re sick, they’re vulnerable, and they’re more likely to fall victim to predators. Hiding is your cat’s attempt to keep himself safe until his body heals.

Even though your domesticated kitty is perfectly safe in his home, his instincts still tell him to seek out a secure place to hide.

Additional reasons why cats hide

Cats don’t hide only because they’re sick, though. Fear can also prompt a cat to hide. This is often evident when you first bring a cat home and he immediately finds a space that’s quiet and tucked away from humans and other pets. Some cats are so good at hiding that they seem to disappear.

Stress can also cause your cat to hide. He might be feeling stressed because of the addition of a new pet or a baby to the home, or other changes like construction on the home or the move to a new house. Most cats will hide out until they’re feeling more confident or the situation in the home has settled down again. Then, you’ll see your cat reemerge.

How to tell if your cat is hiding because he’s sick

Because there could be multiple explanations for why your cat is hiding, it’s important to look for additional signs that your cat is sick. Cats who are sick and uncomfortable might take on a different posture, often hunching over or trying to flatten themselves against a wall. Your cat might have trouble walking or might be unusually irritable, which can be a sign that he’s hurt.

You might also notice dietary changes in your cat. Many sick cats will lose their appetites, and they can quickly become dehydrated. They might experience vomiting or diarrhea, or they might have trouble using the litter box. If you notice that your cat hasn’t urinated or defecated in a day or more, it’s a sure sign that something is physically wrong.

You can also use your knowledge of what’s normal for your cat to look for other signs that something is amiss. You might notice that your cat is squinting, is unusually tired, or is more or less talkative than usual. All these changes can be symptoms of an illness or injury, and they indicate that your cat needs help.

If you’re wondering, “My cat is sick and hiding — what do I do?” then it’s important to take action quickly. If your cat is sick enough that he feels he needs to hide, then he also needs prompt veterinary attention. This is particularly true if you notice any of the symptoms listed above.

When in doubt, call your vet

If you think your cat is sick, call your vet and make an appointment. Your vet can evaluate your cat and help identify exactly what is causing him to feel off and want to hide. Minor issues and pain can prompt your cat to hide, but serious illnesses can, too. The sooner you get your cat to the vet, the more quickly you can start to treat whatever is bothering him. Prompt veterinary attention might prevent an issue from getting worse, and it might even save your cat’s life. Being aware of when and why your cat is hiding can help you better understand his health and tell when something is wrong.

Cats are a bit of a mystery. Unlike dogs, which have the reputation of being human’s best friend, our feline friends seem to view us as a necessary evil. We clean their boxes, fill their water dishes, and buy them trees to climb on so they can get away from us.

And also unlike dogs, cats are natural-born predators — known for being so bad for the ecosystem that it’s best to keep them inside. The arrangement can cause some friction, but we love our cats anyway. When a pet starts doing something out of the blue, we may worry it's not common cat behavior.

You love your kitty. Sometimes, that means agreeing to send them in for cat surgery. Whether it’s a standard spay or neuter procedure, necessary dental work, or something more worrisome like removing a cancerous tumor, you’ll want to ensure you give your furry friend some extra TLC post-operation.

Your feline friend may also need you to be patient with them. Cat behavior after surgery can vary from pet to pet, but they may be slightly shyer, lethargic, or easily irritated for a while. The good news is that your cat should go back to normal — and hopefully wind up as an even healthier version of themselves soon. Knowing what to prepare for can ensure your cat feels safe, loved, and comfortable after surgery.

UTIs are a common and pesky condition in humans. It’s short for urinary tract infection. A UTI is an infection of a part of the urinary system, like the bladder, kidneys, or urethra, as the name implies. UTIs can involve painful burning sensations when peeing. They affect about 10 out of 25 women and 3 out of 25 men at least once, according to the Urology Care Foundation.

Cat parents may wonder: What is the rate of urinary tract infections in cats? Unfortunately, it’s not zero. Cats can get UTIs. The good news is that cat health experts don’t commonly see the issue when treating felines. However, it’s still good to think about the urinary tract when approaching your cat’s health.
