He never cleans himself right after using the litter box. And whenever i am around i always notice urine behind him after he comes out of the litter box. He's 5 months old i am not sure if he'll ever lick himself clean. I used to change the sheets 3-4times (everytime i would notice wet urine stain on them) but now i am just tired of changing sheets so many times. What should i do? Keep changing the sheets or stop looking at the spots my kitten sits on after peeing (deliberately ignoring the filth)?
