A mother cat will teach her kittens to
use the
litter box and most adult cats have no
trouble with it, but it isn't uncommon for a cat to occasionally go on strike against his
litter box.
Kittens learn to
use the
litter box at a very early age from their mother and, as long as you provide enough
litter boxes, fill them with the best cat
litter and you clean them frequently, most cats don't have any
trouble maintaining his behavior into adulthood and seniority.
