We have 3 litter boxes and 3 cats. If we put her in our spare bedroom with a box she uses it. But when she sees us in the yard or decides she wants to go outside she paws at the sliding glass door and eventually goes to the bathroom on the floor near by.
When we first moved in the house there...
One our 3 cats stopped using the litter box and going in the same spot in our dining room.
I believe she is acting up because we let her outside under supervision and now Cry's to go out and pees by (other side of the room in the corner) our sliding door to the yard.
We use cat attract litter...
