In terms of nutrition, what is a major difference between canine and feline diets?

Cats require higher protein levels due to their obligate carnivore status. This is a fundamental aspect of feline nutrition, as cats have evolved to rely heavily on protein derived from animal sources to meet their dietary needs. Unlike dogs, which are omnivores and can derive protein from both animal and plant sources, cats possess unique physiological requirements. They have a higher need for certain amino acids, such as taurine and arginine, which are primarily found in animal tissues. This obligate carnivore classification means that their diet must consist predominantly of protein to maintain optimal health, including muscle maintenance, energy levels, and reproductive health.

In contrast, while dogs do need protein as part of their diet, they are able to thrive on a more varied diet that includes carbohydrates and plant materials. Other options presented do not accurately reflect these differences in nutritional needs, emphasizing why the emphasis on the protein requirements of cats is crucial in understanding the divergent dietary needs of these two species.
