Independently and more recently genetic mutations affect the fact that different carnivores do not feel the taste of sweet food.
Probably due to the fact that these animals are fed exclusively on meat, which has a sweet taste even before the mutation first arose, over time they have simply lost the ability to feel the sweet taste. That is why all of these types of animals are absolutely indifferent to sweets and fruit.
Omnivores that chew the food, on the other hand, the need for carbohydrates, which are an important component for these diets. Their receptors are configured to recognize the sweet taste, remained unchanged.
For many decades, scientists have known that cats are not particularly fond of sweets. In 2005, researchers at the Monell Center sensations, of Philadelphia, published a scientific paper in which he showed that domestic cats have a mutation that affected their taste buds, leaving them unable to respond to the sugar molecules. The same applies to their closest relatives in the wild, including lions, tigers and jaguars.
Many people, owners of domestic cats, can not believe it's true. "When we published our findings devoted to cats, we have received many responses, pet owners said:" My cat loves sweets, you're wrong! "- Says biologist Gary Byuchamp, director of the Center. - Everyone knows that cats are not averse to eat ice cream and cake, but not because of the sweet taste. Simply, these foods contain fats and other necessary components. "
