My cats are messy af. They are always flinging litter everywhere. I have tried a few types of litter mats and I love the “black hole” litter mats but for some reason my one cat likes to pee in them and it’s a huge pain to clean every few days when he does this (he’s medically fine, he just has a few types of things he likes to pee on/in. Vet said it was behavioral)

Are there any other types of litter mats that anyone would recommend to keep my floors neater? Thank you! (Also I use the dustless olive pit litter which is amazing and clumps well)
