PrettyLitter is a special cat litter that changes colors to alert owners of potential illnesses that can be  via the urine in an otherwise asymptomatic cat. According to PrettyLitter’s website, the granules are made of porous silica gel containing the company’s patented health indicators. These indicators cause the litter to change color when blood, acidity and alkalinity abnormalities are detected.

The color key:

Golden yellow or olive green litter: a healthy cat (at least in regard to what can be detected via the urine)

Red litter: blood in the urine

Blue litter: high alkaline content, which may indicate a urinary tract infection

Bright green litter: abnormal acidity, which may indicate a metabolic disorder
