oooooooooooooooh yum, litter box kitty crunchies!
no worries, the cat food usually has more "flavor" in it so it would naturally smell more apetizing when it comes out as well: just like what was mentioned, no need to consult a vet just get the litter box out of the way of youre furbaby..... oh and the dog can really only contract something if the cat has something virul in its system to begin with, otherwise you are fine....... might not want to be accepting of kisses for a while though....lol
