    Modkat litter box odor filter

    My box is used by two cats, and the smell is barely noticeable. I use use an odor powder too, but I those filters really make a difference.

    Best we found in 10 years

    We been through many liter boxes and liners. Had our cat since it was a kitten. Got to say found this brand on Amazon was reading the reviews, bought the whole setup. Liter box and all. We are definitely pleased and won't be changing back. No more blaming it weekly cause it smells soooo bad. This is such an easy, no mess and no smell choice. Thankful cause I love my my cat but not the litter box.
