Last night I noticed this black/brownish looking thing on my cat's anus. I thought it was a piece of feces so I went ahead and tried wiping it off with a tissue. It did not come off. I then tried with a warm wash cloth and nothing.He was getting annoying when I was wiping it. I got closer and held him down and noticed it was attached. It kind of looks like a skin tag of some sort i don't know. Its not on the fur. Its on his actually anus to the right of the hole. very very close to the hole so I am not sure about an anal gland problem, No swelling No redness. Acting normal as far as eating and playing. I have attached a picture. Any idea of what this can be? He is 5 years old and neutered. I am going to take him to the vet I just wanted to check first if anyone has seen or had experience with something like this. Thanks
