2yr old cyst on 18 year old's paw
My 18 year old cat has had a cyst growing externally on his paw for nearly two years. It has never bothered him, he does everything he needs to do and could care less that it's there. Suddenly yesterday it started to bleed and open up a bit. I've done the best I can to keep it clean with peroxide and neosporin. He still doesn't care that it's there, it doesn't hurt him.
This is a holiday weekend, and even if taking him to a vet at his age were a possibility, nothing is open. He gets so stressed out, I am afraid at his age it would do much more harm than good. Even his vet agrees that he has never seen a cat react the way that he does and fears a heart attack.
Any advice you can give me is greatly appreciated. Ways that I can keep it clean, or help it heal. And possibly what I can expect the cyst may do from here on out.
