Litterbox Antics

Hi everyone -

I have a random question. Whenever Jingles goes into the litterbox, Jangles just sits next to it, stares and paws at her. Once she gets out, he attacks her and they start play fighting. Then it starts all over again when Jangles goes into the litterbox.

It doesn't seem like they're fighting or anything like that. And they both use the box just fine (knock on wood). I was just wondering if anyone else's cats do that.

sometimes when meowser is squatting in the box, munch will run over, bat at his tail, and basically harrass him. meowser seems used to it though, munch is a ball of energy.
