Many cancer symptoms in cats are subtle and can be caused by another condition, but if you notice any of the following, it’s a good idea to talk to your vet.
1. Excessive Hiding
Cats love a good hiding spot, but if you notice your kitty is spending more time under the bed or in hard-to-reach places, it could signal that something’s wrong. “Owners often tell me they notice when their cat is ill if they’re usually social but have been spending more time in new hiding spots, or that they stop coming out at feeding time,” says Jake Zaidel, DVM, founder of Malta Animal Hospital in upstate New York and a member of the American Veterinary Medical Association. While excessive hiding is a general sign that something is off with your cat—not necessarily cancer—it’s still a good idea to see a vet, he says.
2. Weight Loss
Weight loss is the number-one cat cancer symptom Dr. Zaidel says he sees. It’s often the sign of a gastrointestinal tumour. “When cats are usually food-motivated but start to turn up their nose and don’t want to eat, that’s very concerning,” he says. Cancer can also cause cats to lose weight while maintaining their regular appetite. If you notice your cat shedding pounds, either rapidly or slowly, make an appointment with your vet.
