My 10.5 lb. cat is very fussy about using a litter pan. With his prior litter pan, he would not go more than once without meowing loudly to have it emptied. It was not possible for me to clean out the litter each time he used it. (I clean it out once a day.) Plus, he was making a mess scratching out litter all over the floor. This larger pan was a godsend for both of us. There is enough litter for him to find a clean area in which to poop/pee. And the sides of the pan are high enough for him to not scratch out the litter all over the floor. The pan is very durable and a good value. I highly recommend it.
