The whole reason I got it was cuz of the funny adult humor on the side & the mat. That just made me laugh & I think it’s genius. The second reason I got it was because no matter what litter box i get or how high it is she finds a way to kick out most of the litter. every.time. I’m losing my freakin mind. That being said even though I have only had it for two or three days there’s barely any litter outside of it & that is a first for me so HALLELUJAH! Not only that I have 3 cats & they each have their own litter box & they are all three completely different sizes from a tiny hairless cat, to a chunky devon rex, to an even chunkier long haired cat & all 3 of them fit perfectly in there. Also ever since I set up this one all 3 of them have been using only this one so that should tell ya something! I like it so much I got another one. If anything changes I will let you know!
