ever since I have known clumping kitter litter is bad for kittens (this morning) i have been worried about Seafa. Now I am happy because I replaced the kitty litter with a non-clumping sort found in the shed. i dotn think it would work even if it were the clumping sort, because the brand is reknowned in ym country for being well, cheap lol. ot much danger, there huh.
