I am 33 weeks pregnant and have not cleaned the litterbox in... over 33 weeks lol. But my husband was cleaning it the other day and he made me go look at it before he scooped. We have two litterboxes, and the cats use one to pee, and one to poop lol. I thought by having 2 litterboxes for 2 cats, they would each use their own, but no, they use one for pee and one for poop... Is that weird?
