Cat people, I have a question: have any of you ever used the KatKit that Jonny Cat makes? It's a disposable pan pre-filled with their regular clay litter. I'm house-sitting next week and I was thinking of picking up one of these instead of taking Cassie's regular box and litter. If you've used it, did you like it? I know I'd still have to scoop it like her litter pan, but the incentive to throw the whole thing away when the house-sitting stint ends is a biggie.

Thanks!
