Patches help me a little worried, any advice? He has a rash on his belly [View all]

[Walleye]

And now he’s licking the hair off, it’s a little line of red spots. Do kitties get shingles? Anybody know anything I could put on it. I don’t know how I would even get him to the vet if I had to, he’s so big and strong, I took him in once when he was about a year old, he was so sick he couldn’t fight back, (infected bite from another cat) so he’s had his shots and his neutering. He seems very healthy otherwise and lively. Maybe I should change cat litter? Any advice? Thanks in advance
