We bought this cat litter box in the hopes that it would make our lives a bit easier with two cats. Neither cat has taken to the box, so we are selling it in defeat. We bought it full price at Petsmart (~$200 after taxes) and it is in brand new condition as we only managed to get one kitty to use it once. It does not come with the silica gel litter, although we have a disposable box, which is incredibly durable and would work as a container to put your own silica gel litter in. They recommend you buy the disposable boxes with each change, but the box seems sturdy enough to handle a few changes, meaning you can buy bagged silica gel litter for cheaper. I tried to upload a video of it running but apparently videos aren't accepted. https://www.petsmart.ca/cat/litter-and-waste-disposal/litter-boxes/petsafe-scoopfree-self-cleaning-cat-litter-box-6677.html?cgid=200153 Asking $50.
