When I saw the catgenie I knew I had to have it. I thought my 8 yr old kitty wouldn't go for it though. We got him at 5 and he's always been very afraid of new people and new things. I was shocked when he jumped in within the first 30 minutes. He doesn't hang around for the cleaning cycle, he hides under the bed. He knows when it's going to clean. He loves the extra clean box. It has been hard for me to keep up on his old box like I should due to medical problems. The catgenie is just wonderful. When I opened the box I thought it was going to be difficult to set up because of everything enclosed in the box but my son had it working in less than 15 minutes. I highly recommend the genie. My bathroom always smells great now too. It's well worth the price.
