On the topic of "doesn't seem like a good idea," I saw a commercial for a new kitty litter. Fresh Step has come out with a litter that eliminates smell so effectively, it's like you don't have a litter box. It features a bloodhound coming over to help the cat find the litter box, as kitty can't smell it. Now, I have never owned a cat, nor been owned by one, so I am not an expert, but it seems to me that if the cat can't find its litter box, this is a BAD thing. Did I miss something?
