Weight loss is the number-one cat cancer symptom Dr. Zaidel says he sees. It’s often the sign of a gastrointestinal tumor. “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. This is why your cat loves your laptop so much.
Sores, lumps, a strange odor, bleeding, or a change in gum color can be a sign of oral cat cancer, particularly in older cats. This cancer sign in cats often goes unnoticed for too long. “We commonly find visible oral tumors because people don’t examine their pet’s mouth,” says Zaidel. “Many oral tumors can be really devastating because people don’t find them until it’s really advanced.” He also suggests brushing on a regular basis. It’s a good idea to watch when your pet yawns or eats, advises Timothy Rocha, DVM, an oncology specialist in New York City. See a vet if you notice something out of the ordinary.

Nosebleeds are never normal, says Dr. Rocha. “With an older cat, a nosebleed is particularly worrisome. It can be a sign of cat cancer in the nose,” he says. “With younger cats, I would worry more about something like a foreign object stuck up there before cancer.” Believe it or not, these cats have better jobs than you.
