Top Warning Signs of Illness in Pets

Our furry friends can communicate very clearly at times. Although Fido and Fluffy don’t speak our language, they usually manage to let us know when they want something, like food or cuddles. Unfortunately, dogs and cats aren’t always quite so forthcoming when they aren’t feeling well. Therefore, it’s very important for you to be able to recognize signs of illness in your pet. Catching and treating a medical issue early can make a huge difference! In this article from Armitage Animal Clinic, a local Newmarket, ON vet lists some common signs of sickness in pets.

Lack of Appetite

Healthy pets have healthy appetites. Some pets can be rather finicky at times, while others will eat, well, just about anything. However, even the pickiest dog or cat should show some interest in their food. If your furry friend isn’t eating, contact your vet right away.


Our four-legged buddies certainly love naps! However, even the laziest pet shouldn’t sleep all the time. If your pet seems listless, and doesn’t want to do anything but sleep, your furry pal may be ill.

Unusual Behavior

Keep an eye on your pet, and watch their day-to-day habits and mannerisms. Any changes in your pet’s usual behavior, routines, or vocalizations can be a sign of sickness. For instance, if your cat is usually a little cuddlebug, and suddenly doesn’t want to be held or touched, you could have a sick kitty.


Just like people, pets can get a bit cranky when they don’t feel well. If Fido or Fluffy seems uncharacteristically grumpy, you may have a sick pet on your hands.


It isn’t unusual for pets to have an occasional upset tummy. However, if your furry buddy is throwing up violently or frequently, contact your vet immediately. Diarrhea can also be a warning sign.

Lack of Playfulness

Our four-legged friends typically slow down as they age, but this should be a gradual change. A sudden lack of interest in play can be indicative of sickness.


These are just a few common symptoms of illness in pets. Keep in mind that our furry companions all have their own characteristics. Ask your vet for more information about symptoms in your particular type of pet.
