hi. i have a cat named WAffles, nd hes a tabby. he has a few small bumps on his front and hind legs. their all bald and oval shaped. their hard and pink. hes had the first one for a while and it hasnt gone away. the other one i noticed today. hes 2-4 years old, im honestly not sure. they dont seem to bother him but hes outside a lot so he may scratch and bite them outside bit i dont think so. hes very fit and not too fat or too skinny. he does fight the other cats that i own a lot, and im constantly pulling him apart from the black cat that lives in my neighborhood. im not sure why they hate eachother but they do... im kind of worried about the bumps. should i take him to the vet or is he okay? and if hes not okay should i separate him from all other cats?
