There are several considerations to factor in when selecting a cat litter, for instance how absorbent and how well the litter controls odor, to more safety issues. Bentonite cat litter is a great blend of clumping cats making it easy to achieve clean litter bins. Mineral cat litter has superior absorptive power and as an added benefit it is often almost dust free and perfect for allergy sufferers. Tofu cat litter utilizes safe natural ingredients and is environmentally friendly as well. Pine cat litter is also a great option as it has a great natural scent and is biodegradable.
