This is a fantastic litter box for a condo or small living area. It has an adjustable timer for the automatic rake with 3 different timing options for self-cleaning preferences. There is no smell as the crystals dehydrate the poo/pee and store it for cleaning in a little reservoir. Very little if any tracking of the crystals. Very easy to clean, it as a counter telling you how many times it has been used that you reset each time it is cleaned. (Great way to monitor your cats toilet habits for health if necessary) My cat was too old to want to change sadly. Dimensions L x W x H 70.2 x 40.6 x 48.6 centimeters New on Amazon - 226.00 I bought this reusable tray instead of using the individual paper trays that you through out each change. Saves lots of money with not having to buy the complete set each litter change, just buy the crystals either on Amazon or Pet Smart. Much easier. It is all cleaned like new and ready to go.
