Dyresjappa is a petstore which sell supplies for cats, dogs, and other animals. We sell catsand of different types. We sell Everclean, Sophisticat, Catrine, and Gresshoppa. Each year more than 2 million tons of catlitter, or close to 100,000 truckloads, ends up in landfills. This litter is not biodegradable or renewable and adds unnecessarily to the waste burden. Biodegradable catlitter packed specifically for cats tends to be very expensive, more so than traditional clay litters, so cost is not a positive factor in their selection. But most biodegradable litters will last longer than the equivalent size of clumping clay litters.
