We have purchased one and giving it a go with our two cats (11 and 9).
We have had a litter tray for a couple of years. Our eldest cat started peeing in the house when I got pregnant with her DD and we have not been able to persuede them other wise since. I hate the litter tray and am paranoid about litter smells.
Has anyone tried it or know anyone who has?
