do you know the breed? I agree with @may24th your kitten might not like the litter. I would try one that is scent free. if the kitten likes that you can mix scent free with other litters to make it slightly scented. another good thing to try is when your kitten does go potty elsewhere clean it up and put it in the litter box. so if it pees. wipe it up with tp or paper towel and just put that in the box. then after it eats or drinks put the kitty in the box. its pee and poop being in there may help.
