We use the pine litter that you can get in the supermarket now, it's meant to be environmentally friendly and it does the job so we'll keep using it. We used the crystals before this and found that we have less mess on the floor these days. You can flush small amounts of the pine litter, or put it on the garden.

One of our kitties uses the people toilet which is fab! The other kitty isn't so good at using the toilet so we have to keep the litter for her.
