This is the paw wax that I have for Zoey:
linkIt helped with the slipping a little, but not really enough to make me perfectly happy. It helped for a couple hours - it was funny because as she walked around, I could hear the wax against the wood floors. She has fumbled with the wax on, but at least she hasn't had a major spill with it on.
When I put it on one night her paws felt softer for like a week after that. I am not sure if it would affect their heat sensitivity. I would think if you use it too often it would be bad, but if you only use is it only every once in awhile I think it could be good.
