Our cat has a large fleshy lump right above his right shoulder blade and he's lost alot of weight. We noticed the lump a couple of weeks ago and have been monitoring him. His last vacine was about a year ago. He's still very active and playful, and he's still eating. I was searching the web for information on cat's and lumps, and I got really scared after reading about the possibility of our cat having cancer. I stopped crying long enough to make him an appointment for Saturday with his vet. Does a lump and loss of weight usually mean cancer? Please tell me it doesn't.
