Hello. My indoor cat (10yr, male, neutered, 13.5lbs) has had a small bump on his skin for 1+ years. Small enough I had trouble finding it to keep an eye on it. Yesterday, I noticed it has grown maybe 3x or 4x in size and is bleeding. It is behind his front shoulder blade. It is very raised, I can feel it over his fur when I pet him. I was wondering if this looks like a normal cat bump/wart, or if it is concerning enough to get it looked at in-person. Photo attached. Thank you.

Thank you for providing a picture of the bump on your cat, it's very helpful! It could simply be a benign growth, as it looks like it could be one in your picture, but unfortunately I cannot make the determination for sure without seeing him in person and doing tests on it. It is a bit concerning that it has grown up to 4x in size and is bleeding. It could be bleeding because he is scratching at it, but again I don't know unless I see him in person. Due to the fact it has grown in size and is bleeding for some reason, then yes I do think this is concerning enough to see the vet. It would be good to get the exact diagnosis of the bump; in addition, your cat is 10, which means he's a senior cat, and there is always a risk that any bump in a senior cat could be malignant. I'd give your vet a call to make an appointment. I hope this helps!
