What is the significance of ash in cat food?
Ash is a general term that refers to the non-combustible residue that is left after burning a sample of the food for at least two hours at 600 degrees C (1112 degrees F). This ash contains calcium, phosphorus, magnesium and other minerals that are essential to a complete and balanced diet. The total amount of ash does not reflect the proportion of individual minerals. Some cat owners and veterinarians are concerned that ash may contribute to the development of feline lower urinary tract diseases. Research has shown that this is not true, and some diets high in ash may even be helpful in preventing some types of urinary tract disease.
