I’m always reading forums on here to answer my questions and it’s my first time posting on here. I have a 10 month old male sphynx! His name is Gollum. I was bathing him this morning and noticed these marks on his neck. They look like a cluster of blisters they’re a little yellowish. It didn’t seem to bother him, I washed it with a warm cloth & it didn’t even phase him. He didn’t have it last night, so it popped up overnight. He’s eating and drinking very little this morning, as well as just excessively sleeping which isn’t normal since he’s very active throughout the day. I took him to the vet, and they couldn’t tell me what it was they did remove it to run some tests on it. But I figured I’d try to see if anyone knows anything about it or maybe has experienced it.
