Thats fair. Air filters are on my post moveout checklist for properties anyways, so I figured if there was a mess in the garage then there might be one in the house.I don't think the cats ever came into the house, no smells. I am gonna have the garage epoxy coated and keep the deposit. I'll come out of pocket a few, but it will be worth it in the long run. If that doesn't do the trick, I'll have the walls painted up and take them to court. lol. I kind of think they aren't planning on getting deposit back anyway. They didn't mention it since they left. I will get a forwarding address though and send them an itemized list and pics.
