My fiance got a new kitten in October, and he was litter trained when we got him, which we thought would be perfect. We continue to use the same litter as he's used to: World's Best. When our little man goes pee, his genital region gets all wet; needless to say, that when he's done, he sits somewhere in the apartment-the bed, the couch, the coffee table-and leaves his mark. The apartment is really starting to smell despite our best efforts to clean up after him. It doesn't matter how much litter is in the box-this happens every single time. Any suggestions? Thank you!
