We've had the ModKat litter box for about 1.5 years now and couldn't be happier. We live in a small house with 3 cats and a dog and it was very difficult to find a place to put the cat box where #1 it wouldn't be seen and #2 where we wouldn't be stepping on all the litter the cats track out. ModKat certainly fixed all our problems. It's decent enough looking that I don't have to worry about how unsightly it is- most people don't even know what it is- and we no longer have cat litter all over the floor after every use! After a year and a half I have probably saved hours from no longer having to sweep up cat litter five times a day! It's also great because our dog can't go and pull out any yucky "treats"!
