My cat Misty has been acting kind of weird lately. It sounds like she has been trying to hack up a hairball for the last couple days. It mostly happens when she is resting or sleeping at night. She will constantly wake up and dry heave but nothing ever comes up. During the day she is fine and plays and eats like normal. Right now she is just chilling on my bed grooming herself and watching me. I bought some hairball gel recently and have been giving her that, but it doesn't seem to be helping. I'm going to make her an appointment for the vet first thing Monday morning to see what the problem is. She hasn't really been pooping so I'm worried she is clogged up. Is there any home hairball remedy that I could try that might be better than this one I bought?
