Help, why my kittens love to sleep in litter box 😂

I always scoop after their business.
Sometimes they sleep in their carriers, on carpet at cabinet... but why litter box also sleep? Someone make me understand please. Issit because of the littersand texture?

may i know if you prepare how many kind of food for your cat?

I have RC for kittens and 1 kind of wet food.
on majority days, they are eating RC.
twice a week eat wet food.

i was thinking, will they get bored by eating these only?

Alamak, my cat suddenly puked.... can see kibbles one dot one dot from it
