Why dogs and cats should never eat cooked food
With a very few exceptions (such as seriously ill animals with compromised immune systems) dogs and cats should not eat cooked food.
What heat does to food
Why enzymes are so important
Whereas human saliva contains lots of enzymes that aid digestion, canine and feline saliva doesn’t. Dogs and cats have short digestive tracts and very strong stomach acids. The enzymes in raw food are vital to their digestive process.
So what happens if they aren’t present when the food reaches the stomach?
Cooked food forces the pancreas to work harder and to draw other enzymes from the bloodstream. This can leave a dog or cat physically vulnerable because the enzymes in the blood are supposed to be protecting the body, not aiding digestion. In a nutshell, cooked food can seriously undermine the animal’s immune system.
A number of studies also show that the pancreas enlarges on a diet of processed food. An enlarged organ means excessive function. Excessive function can lead to degeneration. It is a similar story when it comes to amino acids. Cooking at high temperatures alters the arrangement of these acids, making half of them unusable by the canine or feline body.
