I found this black lump/bump on Magnus's back leg. I thought it was a tick at first but it wasn't. He didn't seem bothered by it at all even when I examine it. I'm taking him to the vet today to get it looked at but wanted to see if anyone saw this before.
It's soft, totally black, and I think there's some hair sticking out of it too. Could it be a wart? Picture isn't totally clear but I couldn't get the phone to focus too close..
