My husband pisses me off because although he loves his cats more than anything, he procrastinates inconceivably about cleaning their damn litterboxes! I used to clean them everyday before I got knocked up, yet if he does it once a week (after me trying everything in the book - sweet-talking, begging, bribing, screaming, threatening), that's a lot for him.

I do have one litterbox that one of my cats loves (the other hates it so we have a separate one for her). It's called the Smart Cat Box (http://www.smartcatbox.com). It doesn't use regular litter and it seems WAY more hygienic. The pee filters through a grate at the bottom into a container, which you just pour into the toilet then rinse out. The poo doesn't stick to the litter, so you just scoop/flush. The litter itself just needs to be rinsed every 2-3 months and replaced every 6 months. It's a lot cheaper than a regular litterbox system, and since the litter is just safflower seeds and the pee doesn't remain in contact with it, there is no smelly chemical reaction. Less tracking of litter in the house, too.

But as I said, one of my cats HATED it and she ended up ruining the carpet in one of our rooms until we finally got the hint and gave her the old litterbox back.
