A: No, unlike some other litters on the market, Cats Incredible litter does not contain forms of borate or boric acid. Borates and boric acid are used in such products as laundry detergent, fungicides, insecticides, and teeth bleaching chemicals.  Studies have shown that borates can be irritants to the eyes and skin. Chronic exposure to borates can produce eye irritation, cough, and skin rash.  Higher doses of exposure have been linked with seizures and convulsion.  In some countries, including the European Union, borates are considered to be a class 1B carcinogen and mutagen and have been banned in the use of all personal and cosmetic applications.  Therefore, we would not use borates in our Cats Incredible formulas.
