EVERYTIME...yes everytime I pick up the lid, TWO cats, clayton and whispers'd vroom to wait BY the litterdome... a second after I shove the last clump out of litterbox, whispers JUMPS right into it and go phoooey. *thanks meowmie! I know I'm helping you too....* then clayton goes in, he seems to know he's waiting in a line. I AM NOT kidding!!! *gets up right after whispers gets ou and passby him*

so I wait until they both are finished...then I scoop them out! we're even.... they can't go again in another few hours! humph!
