Kitty wouldn’t bury poop

Olivia

I have a kitty of 3 months old who wouldn’t bury his poop. The litre box is big enough but he scratches on the litter box and this is his second litter box, but he still does the same.

I tried to teach him but still nothing works .

Anyone experienced such and what did you do about it ?

I know this is the wrong forums for this but I need help.
