6 Common Signs of Sickness in Cats

If you have a cat, you may have noticed that kitties can be quite mysterious. Our feline friends are often particularly secretive when they are feeling sick. There is a good reason for this: when Kitty lived in the wild, showing any signs of sickness could attract dangerous predators to her. Your housecat may live a pampered life, but she is still a creature of instinct, and may naturally try to hide signs of sickness. Therefore, it’s up to you to know how to recognize the warning signs of illness in cats. Below, an Isle of Palms, SC vet lists some common symptoms of feline sickness.


Cats often don’t feel very sociable when they are sick. It’s normal for kitties to take naps in quiet spots, but your pet should emerge by dinnertime. If Fluffy doesn’t want to leave her hiding spot, she could be sick.

Poor Grooming

Fluffy is normally very diligent about keeping up on her beauty regimen, but her daily grooming routine may fall by the wayside if she feels ill. If your cat’s fur starts to look greasy, matted, or dull, you could have a sick pet on your hands.

Litterbox Mishaps

If your cat suddenly stops using her litterbox, she could be ill. Changes in the frequency, amount, texture, or odor can also be symbolic of sickness in kitties. Straining to urinate is another red flag, and can indicate a very serious medical emergency in cats.


Just like people, kitties can be a bit cranky when they aren’t feeling well. If your cat starts acting aggressive, she could be ill.

Change in Behavior

Any change in a cat’s normal behavior can be a warning sign. For instance, if a playful, sociable cat suddenly withdraws, there could be something going on with her health. Changes in vocalizations can also be indicative of illness. If your pet is normally quiet, and then suddenly starts meowing continuously, she could be sick.

Change in Appetite

Fluffy can be a bit fussy, but even if your kitty has decided she doesn’t like her dinner, she should still be interested in eating. A decrease or increase in appetite or thirst is another red flag.
