my cat rake her paw on the top of her litter box everytime i transfer the litter?
You've be fooling around with HER box. She's just marking it again beside the scent glands in and around her paws.
she's just feeling it out and checking it out...if the litter isn't verbs or up to par they will go somewhere else...lol it's not an issue just a preference
The cat is just happy and is just showing how it feel.
