What I wouldn't give to eliminate (pardon the pun) cat litter boxes in my life ! With three cats all using one box I have a full time job keeping it clean. Yes I know how lucky am I that they share one box. The idea of a cat using the human toilet has obvious appeal but this article really made me rethink my admiration for the cat owned who've managed to train their fur babies to use the loo. Perhaps it really isn't a natural thing for a cat but the number one (pardon another pun ) obvious negative about it that you can't monitor kitty's health by keeping an eye on their elimination habits. This is often a critical first sign your cat is unwell.
