We've got multiple boxes but Ashley still insist she pees infront of the box. I put a plastic box there to capture litter so it's not going onthe carpet. She's been doing this since before Jake. I thought it was she didn't like the litter (crystals) so I went to a sand like scoopable. She quit for a while then started again. She's healthy so I don't know why she prefers out. Could it be the cover?
