My rescue cat, Pebbles, arrived on Monday and decided that she wasn't going to use the litter box, she didn't like the crystals. She made a decision to use my bathroom floor, obviously not on the same page as me. However, I bought some woodchip litter, which I laid on top of the Fit litter and, hey presto, she has obliged, ( albeit right at the entrance to the litter box) I hope she'll eventually get over this initial problem, it's early days really.
