Chapter 5: Taurine: The Essential Amino Acid for Cats

Taurine is critical for cats because they cannot make enough themselves. Deficiency can lead to a serious heart condition (dilated cardiomyopathy) and retinal damage, and it is entirely preventable through diet. Cats eating complete commercial food are generally protected, but risks arise with unbalanced homemade diets, some poorly formulated raw diets, and certain dog foods fed to cats long-term. In Malaysia, where home-cooking and raw feeding are popular, this is a genuine concern worth discussing with your vet. Taurine is water-soluble and heat-sensitive, so cooking methods affect content. Dogs can also develop deficiency in rare cases, particularly on unusual diets. If your cat eats anything other than a complete cat food, ask your vet whether taurine supplementation or a diet change is appropriate. Do not self-prescribe based on internet forums.
