Well, not sure about with a kitten, but T & P have been using Tidy Cats Multiple Cat formula for years and years and years, almost as long as clumping litter has been out, and they've never had any problems with it. I know people get concerned about them licking the litter off their paws and such, but T & P have never had any problems. And I also don't know how any could still be on their paws because it's always all over th entire basement!

I think this litter works great because I very seldom notice any odor at all. The only thing is, yes I have 3 litter boxes, but they are spread out through the whole basement, not near each other at all, which I'm sure helps disipate the odor somewhat. I also have some of those lava rock odor absorber things. So far I only have two, each hanging over a different litter box, but I'm looking to get another one. The first one I got at a pet show, the second one I got at Restoration Hardware. I don't know how well they would work in a steamy environment like a bathroom (with the shower and all) but it might be worth a try to buy one of those also. I know you can find them on the internet too, but I don't have any specific links right now.

Good luck!
