I have been using the ModCat top entry litter box for 2 years now and I love it. I remember open litter boxes that definitely smelled worse, made a whole lot of mess, and were kind of disgusting to clean. Granted newer cat litter has all kinds of odor control, but they are mostly clay-based. Since I have a septic system this kind of cat litter can lead to problems. I am using the world's best cat litter, which is corn-based and has no chemicals or perfumes added. It works great but can be messy in an open litter box. To top it off, the top entry litter box keeps my dogs away from the litter.
It really helps with my spraying male cat. He can reach over the top of the Modkat litter box when he urinates. This spray helps to control the odors and makes cleanup more pleasant.
this litter box creates absolutely no mess at all. I love it
Stain + Odor Remover
I was skeptical of any spray working. One of our girls doesn't squat to urinate. After a while, even after wiping the liner ,I could still smell the oder of urine. I spray the cat box with the stain and oder spray from Modkat and it killed the oder. Best part is it doesn't have a scent, so our cats aren't affected by it. Great product!
