I'll go to the vet if I need to, but trying to avoid that. He gets wet food daily  and uti dry food. I started giving him apple cider vinegar this morning, any other home remedies?

Take him to the vet. Dont waste his time or yours with homeaid recipes. Can get serious if not treated. Nothing to mess with. 

You will end up having to get a tomcat cath put in him if you don't get them taken care of.  Go to vet earlier instead of later.
