actually only one of the cats is a bad kitty, she is not clean, nor does she clean herself, and when we changed litter boxes to a igloo shaped box, she refused to use it and shitted on the couch, we tried to train them to go outside, but you know how training and cats goes (they are far to fucking stupid to be trained IMO).
someone does need to change the box, like every fucking day, they day i clean it is the day I see what a 2 3/4 inch 12 gauge shell does to a domestic cat (my $0.25 solution to my feline problem), I already know what happens to a fox, and a cat is smaller, so i have a pretty good hypothesis.
