How fast acting is cancer in cats? I took my cat to the vet today, and he says that she likely has cancer. She was acting normal just a week ago though! To clarify, since last Thursday I've noticed that she is not eating or drinking on her own, not using her litter box, is lethargic, and is seeking damp, secluded spaces. It's just shocking to me that these symptoms have popped up so quickly.
