I was hesitant at first, not sure if my cat would use this as prior to purchasing it I was using a large plastic storage bin.  She has an option to go outdoors but seems she would rather jump thru a ring of fire to use a littler box SO, she is using it! :)  It seems to be keeping my dog from helping herself to the "treats" in the box as well!  I like the hinged top that makes it easy to clean.  I also highly recommend the "Slide" cat litter because it truly does NOT stick to the sides of the box.  (a little more pricey but worth it to me).
