- Protein
Cats, being true carnivores by nature, require food with far more protein than dog food. Although some brands and types of dog food have higher protein levels than others, even these specialized dog foods do not meet the high protein levels required to keep cats healthy.
The protein content of most dog meals is 18-26 percent “As-Fed.” For cats, however, I normally recommend aiming for at least a 30-34 percent “As-Fed” protein percentage, with a 40-50 percent protein canned cat food as an optional supplement.
