This is the one on her warm side. It's her most recent addition and it does line up with when her activity problems started. At least as far as I recall, I did buy it because she ruined her previous (albeit cheapo one I should've replaced sooner, it was cardboard) hide when she tipped her water dish.

I've seen her use it but I don't want to discount it from it being the problem. I'll try adding some paper towels to kinda buffer it up and see if that helps?
