I tell everyone I know who has cats about this product! I started with the Tabby Package, but have since ordered the dome as I was just adopting my kitty and didn't know if she'd like the dome or not, but in her previous home she had a regular litter box with a dome. I highly recommend the dome if your cat isn't scared of going inside an enclosed space as it helps retain the granules; she does still track some out and they do stick to her paws and I find them elsewhere in the house, but I'd rather find granules and know that kitty isn't tracking litter everywhere. I LOVE the fact that I don't have to worry about scooping litter and making sure she has a clean box! Was very easy to set up, too.
