Cats can get sick all the time with many of the same ailments as pet parents. However, symptoms for cats can be much different than they are for humans. Our cat symptom checker is a great way to figure out what may be wrong with your feline friend.

When cats become sick, they can’t tell us with words. Instead, cat parents need to be vigilant, keeping an eye out for any symptoms that could point to illness. It also helps to stay ahead of the curve by giving them preventative medication like Advantage Multi for cats. This useful chart breaks down cat symptoms by area of the body, then tells you what each symptom could mean.

Our cat symptom checker is a good place to get started identifying what could be wrong with your cat, but always contact your veterinarian for final diagnosis and treatment solutions.
