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.

Have yet to receive this package and Modkat support is non-existent.

Hi Kellie, our apologies your package has not yet arrived! The tracking shows there was a delay in transit, however your order is scheduled for delivery this afternoon. We have followed up via email, please email us at support@modkat.com if any further assistance is needed. Thanks for your patience, we hope you and kitty enjoy!


Haven’t noticed a difference in odor control.

Hi Cheryl, for optimal performance please be sure to place filter under direct sunlight (2-3 hours per side) monthly. The filters can be recharged up to 3 times before they need to be replaced. With proper care, the two Modkat Bamboo Charcoal Filter packs can last up to a year. When the filter is finished, the granules can be recycled into plant soil.
