Biologically appropriate pet foods not based in science

Biologically appropriate generally means that the dog and cat foods are rich in animal protein and fat.

Many biologically appropriate pet foods are marketed as modeled on wolves and wildcats diets and therefore closer to what dogs and cats would natural consume. However, these nutritional claims haven’t been verified by empirical methods, said Emma Bermingham, PhD, senior research scientist, AgResearch. (See video below from Petfood Forum)

Some people have gravitated towards nutritional trends like the caveman diet, which purports to model itself on the foods available to early Homo sapiens living as hunter-gathers. Likewise, pet owners have developed an interest in what are called biologically appropriate dog and cat foods. In general, this means that the pet foods are rich in animal protein and fat, said Bermingham.

“So, from this there is a bit of a philosophy or belief around what we should be feeding our pets but there's actually very little science to support that,” she said. “What we're trying to do is understand what are pets need in terms of nutrition and then look at what the wildcat might eat in the wild to try and understand the difference between the two.”

Effects of domestication on dog and cat biology

Domestication seems to have influenced cats and dogs differently. The genetic code for domestic cats still bears similarities to wild felines, including cheetahs and lions, she said. Dogs however, seem to have faced evolutionary pressures that caused them to diverge from wolves.

“When we look at the dog it's a lot more complicated,” Bermingham said. “So, while there are huge similarities between dogs and wolves, there are a couple of metabolic adaptations that have occurred that suggests that a dog is certainly not a wolf necessarily. What we're trying to do is look at the nutrition and understand how feeding your dog like a wolf might actually impact the dog’s health.”
