Is dog food good or bad for cats?

Cats are obligate carnivores: they must get certain nutrients (taurine, arachidonic acid, preformed vitamin A) from animal tissue, so a complete, balanced cat food should always be the base of the diet. The food on this page sits in the "limits apply" zone — fine in small amounts for most cats, but easy to overdo. Treats and extras of any kind are best kept under roughly 10% of daily calories, and this one specifically needs the rules below followed.
