Review on Enhanced Basic Litter Pan with Zeolite Filter: Ultimate Odor Control Solution by Kathy King

I had to buy this particular cat box because it had a 'ramp' to climb into. Last summer my cat was attacked by a dog and she briefly lost most of her back legs. Unfortunately, these filters do not fit the Booda Dome, even though it says so on the packaging. But this is the closest I've found and due to the shape it takes two of these to fill the filter hole area on the hood. My cat is 15, I hope she leaves her alone and doesn't pull her out. Two of them seem to help with the smell. But I also dig a lot. If you need a Booda dome filter. It's your best choice until you do something special for that litter box again.
