litterbox rolling

ok here's an odd one for you, Oreo likes to knock some of his litterbox litter out onto the floor then play in it. he *has* toys so this one confuses me. any idea why he does this? i'm begining to think he might just be insane

hmm. that is a new one. I know that cats like to roll in loose dirt sometimes. At least mine does when I let him in the yard. I wouldnt see this as a sign of his being mentally healthy or not. Cats engage in many unique behaviors that may seem strange.
