I don't use litter liners either. My cat will tear them to shreds. Unlike many who have already posted, I also cannot just toss the litter or anything to do with his litterpan into the trash can. I did that one night and woke up to a litter mess, with a pitty piss pile in the middle (oh, and it was right on the carpet too...). It was funny, but ticked me off a the same time.
