I put a post on here a couple of weeks ago, we had a stray kitten that we had taken in that was having alot of dierra, thank goodness his is all better from that but we have another problem with him now, I think he has an ear infection, his left ear has been running. I was wondering if this would be contagious to our other cat? I took a Q tip and put a little perioxide on his ear and seem to have helped a little, should I be doing that? This is a kitty that stays mostly out side but we do let him in some, our other cat is an indoor cat, and I dont want to risk her to getting sick also. we are having alot of financial problems right now and cant take this kitty to the vet, so any advise that I could get to doctor him at home would be greatly appericated.
