We started using Catspot in February 2018. We were given a free sample bag at the NHRA Phoenix Test & Tune Winter Warm Up, courtesy of Tommy Thompson Racing, Marsha Waz Roberts, photographer and fellow Top Fuel Dragster Team, Scott Palmer. From the very first use, Nico, our American Domestic Short Hair/Bobcat hybrid loved it! We love it because he doesn't track it out of the cat box, (he has very big feet), and there is no smell. We scoop out solid waste every 2 to 3 days without clay dust or smell in the process. It lasts 2 weeks easily and then cleans out of the box all in one easy pour into a trash bag. Living here in Arizona, you occasionally get packrats. (Cute, but destructive critters). We took some of the used Catspot and sprinkled it along the base of our block walls and around the rocks decorating our waterfall in the back yard. We haven't been troubled by a packrat since and our roses have been blooming like crazy. We can't smell it, but the critters can. It is a great biodegradable product. Thanks Catspot from us and Nico.
