Cat litter are made of different types of materials. Clay-based bentonite is one of the most common materials in clumping cat litters. Strong clumping, high-quality and natural bentonite cat litter, such as Best Friend Cattia, is easy and lasting to use. Biodegradable cat litter is made from compostable, renewable natural material, e.g. wood, which is used in both clumping and non-clumping litters. When choosing ecological, environmentally friendly cat litters, it is good to note that the often slightly more expensive, clumping litter is usually easier to use and ultimately also cheaper in use. Pellets or similar type cat litter made of the cheapest material tend to break down easily into moist crumbs. The absolute number one among non-clumping cat litter is silica cat litter, which is made from diatomaceous earth , which has excellent odor and moisture binding properties. When the litter dries, the moisture evaporates from it, locking the odors firmly in the silica cat litter, so after a while the cat litter is dry and fresh to use again. Because of this, the same slica cat litter can be used for weeks.
Cat litter is available both unscented and scented. When choosing scented litter, it is recommended to use mildly scented cat litter. The mild scent covers the smell of cat pee and keeps the environment fresh. Too strongly scented litter can completely drive the cat away from the cat litter box or even cause allergic symptoms in a sensitive cat. The owner of a sensitive cat should prefer sand that is unscented and made from as natural a material as possible.
