I think the sneezing was his sinuses acting up because mine was sneezing around the same time I was having trouble with mine, he hasn't been sneezing so I guess that was it. I'll be sure to keep my room swept just in case it was dust.

I keep my door closed so the fleas are only getting there because of me so to solve that I'm going to try to eat garlic more often. I heard it keeps fleas and ticks away so it's worth a shot.
