Taurine requirement of cats is . . . . . . . . mg/kg DM in diet

Answer: Option B

Taurine requirement of cats is 500 mg/kg DM in diet.
Taurine is exclusively found in animal-based proteins. It is critical for normal vision, digestion, heart muscle function, to maintain normal pregnancy and fetal development, and to maintain a healthy immune system. Taurine is an essential amino acid in the cat.
This value is in agreement with the previous estimate and approximates a taurine concentration of 500 mg/kg of dry matter in a commercial cat food.
