It’s common knowledge that cats cannot thrive on dog food due to inadequate taurine levels in dog food, resulting in cardiomyopathy.
Taurine deficiency in cats will also cause retinal degeneration. Once generalised retinal atrophy has occurred, there is no reversing the disease.
Taurine content is high in milk, liver and shellfish. The daily requirement for the cat is 35-56mg.
