Cat Urine Includes, But Is Not Limited, To Three Constituents
Cat Urine consists of mainly three parts: the Urea, the Urochrome, and Uric Acid. The Urea is what makes the urine sticky and allows the other two parts to remain for the unpleasant color and odor. The Urochrome gives the urine its ugly yellow color, which stains carpets, furniture, the walls, and anywhere the cat sprays or urinates. The third part, Uric acid, consists of salts and crystals that give off the extremely pungent odor. Also, if the cat continues to urinate in the same area, the scent will continue to compound causing the entire house to overwhelm occupants with the offensive smell of cat urine.
Cat dander particles are the smallest of major allergens. At 2.5 to 10 micrometers, they’re smaller than dust mites and dog dander. Cat dander is also small enough to become airborne and become absorbed within the walls, carpet, upholstery, clothing, and enter a person's lungs. These allergens can linger in your home, causing you symptoms months after the animal is gone.
Used cat litter contains several chemicals, such as ammonia, amines and mercaptans (thiols). These are gases that are discharged from cat urine and feces, which degrade in stages. During the first stage, ammonia is formed, then amines and mercaptans.
