I had a very interesting comment on my posting "Munching Monday: The Pastry Challenge" last week stating that cats do not need any grains in their diet because they are obligate carnivores.
The definition of an obligate carnivore is: "An animal that necessarily subsists on a diet consisting mainly of meat, because it does not possess the physiology to digest vegetable matter. Such animals may consume other materials (vegetable or mineral) for non-nutritional purposes." - Wiktionary
I completely agree about cats not needing grains in their diet. But, I do believe that it is okay for them to have some grains in their treats for "non-nutritional purposes." I look forward to hearing what you think! Please feel free to comment below.
