I HAVE ONE!!!

My parents bought me & my hubby one for our anniversary. (so sentimental) They work GREAT! We just have one cat and it's perfect for her. If you were going to have more than one cat, I would suggest getting the Deluxe size (there are two sizes) or two small ones. It really cuts down on scooping time and the difference smell wise is worth it all!

When we first got it, we set it up beside of her regular litter box. She automatically began using it on her own, didn't go near the regular litter box. They're so clean, and cats prefer to do their business in clean litter.

Good luck . . . hope your mom finds the PURRFECT kitty!!!
