Never as a diet — cats need taurine that dog food lacks.

Cats hide symptoms — don't wait and see. Even small amounts of certain substances can be fatal to a cat. Act fast.

Verdict
Cats are obligate carnivores with specific nutritional requirements that dog food does not meet. The critical deficiency is taurine — an amino acid cats cannot synthesize in sufficient quantities and must obtain from diet. Taurine deficiency causes dilated cardiomyopathy (DCM, a fatal heart condition) and central retinal degeneration (leading to blindness). Dog food also lacks sufficient vitamin A, arachidonic acid, and niacin for cats. A single meal of dog food won't cause harm, but using it as a regular diet is dangerous.
Symptoms to watch for
- • no immediate symptoms from one meal
- • heart failure (dilated cardiomyopathy) from chronic taurine deficiency
- • vision loss (central retinal degeneration)
- • poor coat condition
- • growth failure in kittens
What to do
Feed cats a complete, balanced cat food formulated for their life stage. If your cat has been eating dog food, transition to cat food immediately and consult your vet about taurine supplementation.
