One of my cats doesn’t like to go outside so he always uses his litter tray. He only poos during the night so I can’t pick it up until the morning, by that point the whole of the downstairs stinks. I scoop out his tray every day and do a full clean once a week. But I feel like the house always smells of dirty litter.
his tray is under the stairs so there is a door with a cat flap, however he will not use the cat flap at all so unfortunately I have to leave the door slightly open so that he can get in. I also changed litter to a clumping one, I used to get the stone type litter but now this one has a texture like sand and clumps really well. But my house always stinks. What can I do? Does anyone have any suggestions?
