Over the past decade, a number of products have entered the cat litter market as “alternative” litters. The chief claim of many of these litters is that they are made from plant-based or recycled materials, as opposed to clay, the basis of “traditional” kitty litters. As with most products or groups of products, there are 288 both advantages and disadvantages to using alternative cat litters. One advantage that makers of these specialty litters feel appeals to cat owners with environmental concerns is that alternative litters – because they are made of biodegradable substances – present less strain on landfills. Some brands are even marketed as being “compostable” and/or burnable. Additionally, alternative litters are often give off little or no dust, which could be a benefit to a cat with upper-respiratory issues. “Our general advice to owners of asthmatic cats is to limit environmental exposure to potential irritants of all kinds,” explains Carolyn McDaniel, VMD, a consultant with the Cornell Feline Health Center. “This includes aerosol cleaning agents, perfumes, cigarette smoke … and dusty cat litter.” Another benefit of some alternative cat litters is the lack of artificial fragrances or harsh chemical additives. Dyes and deodorizers found in some cat litters have been linked with contact allergies in cats, says Dr. McDaniel. “Any cat with dermatitis lesions affecting the paws should have the litter type evaluated for possible allergies.” Possible Drawbacks. One of the biggest potential downsides to using an alternative kitty litter involves owner convenience: Not all of them are clumpable or scoopable. Cat litters that dont clump must be emptied and replaced more often to keep odors under control. The inability to scoop urine clumps from certain alternative litters may mean that owners will have to change the litter more frequently to avoid undesirable odors (and could incur a higher cost by simply using more litter, more often). And, finally, theres a potential “tactile” issue with alternative cat litters. The reason alternative litters are “low-dust” is that their textures are often courser than a traditional clay litter; many alternative litters are in pellet form. “Cats are sensitive to all kinds of sensory input,” notes Dr. McDaniel. “Although individuals vary, cats in general seem to prefer soft, fine, sandy material in their boxes.” So some cats may not like the rougher texture of certain alternative litters. New litters are appearing on the market on a regular basis. Some varieties are offered through national pet store chains, while others are available regionally or through Web-based companies. The following is a current list of some types of alternative litters, categorized by their primary ingredients. Wood-and Grain-Based Kitty Litters. Of the alternative kitty litters appearing on the market, those made from wood pulp or shavings are the most popular. Wood-based varieties are made from recycled shavings, which are kiln dried to remove aromatic oils, and then compressed into pellets. Feces can be scooped out, while urine is absorbed by the pellets, which swell on contact. Moistened pellets then dissolve into a wet wood dust. Grain-based litters are made primarily from wheat, oats or corn. According to manufacturers, odors are eliminated by “natural enzymes” contained in the grains. And, if your cat ingests these products, manufacturers say the litter will pass safely through the cats system. Other benefits of these grain-based kitty litters are that they are clumpable, and some are flushable. (Note: A 2006 California law recommends disposing of cat litter in landfills rather than flushing it, in order to limit contamination of sea-otter habitat with harmful Toxoplasma gondii.) Paper-Based Litters. Kitty litters made from recycled paper come in both pellet and granule forms. Recycled paper products tend not to cling to cats paws, making them a popular choice for kittens, recently declawed cats and other post-operative care, say manufacturers. Many of the products also claim to be safe to incinerate, compost and flush with septic systems. Making a Change. If youre interested in switching over to an alternative type of kitty litter, Dr. McDaniel suggests giving you cat(s) a choice: “The best idea may be to provide a smorgasbord of litter types in a number of boxes to find out what a particular cats favorite is.” Another method is to put roughly one inch of the new litter on the bottom of the cats litter pan and top this with three inches of the cats regular litter. At every litter change, decrease the amount of regular litter covering the new, alternative litter until the use of the old litter has been phased out completely. Of course, no matter what the possible health benefits might be with an alternative litter or how attractive the pricing, a litter is only as good as the use it gets. The trick is to find a litter that both you and your cat will like.
