I’ve had my squirrel for 6 weeks now, and he’s about 9 weeks old. I noticed a patch of fur missing on his head about a week ago. I’ve watched it and just today I noticed that it may be getting a little bigger. I’m nervous that he could have mites. Does anyone know what it could be? He doesn’t seem to be scratching himself very much. He was for awhile, so I got him flea spray, and he almost stopped scratching completely. Can fleas make them lose fur? Should I be concerned?I’m trying to upload a photo..if it doesn’t work let me know and I’ll try again.
