According to the vet, he only had a serious case of earmites. The girlie later found a few fleas on him, which resulted in a bath. No problem. Still doing well. The earmites were really bothering him, so we cleaned out his ears.
Then yesterday, he just wanted to sleep. He isn’t eating. No indications that he swallowed something he shouldn’t. We’re going to go get some kitten milk and beef baby food today and syringe feed him if necessary. He is definitely going to the vet – poor little guy.
