Cats' inability to taste sweetness is related to their own genetic defects. This is mainly due to the deletion of the gene segment that forms sweet taste receptors in cats, resulting in cats being insensitive to sweetness and even unable to taste sweetness. With the exception of cats, almost all other mammals can taste sweetness.

The dangers of cats eating sweets:

1. Oral diseases. It will increase the chance of cats suffering from oral diseases. Sweets are the food that many kinds of bacteria like, which greatly accelerates the reproduction rate of bacteria in the mouth.

2. Indigestion. Sweet foods will increase the burden on cats’ digestive systems, because cats use protein foods as energy rather than carbohydrate foods.

3. Easily gain weight. Eating too much sweets can easily lead to obesity, and cats are no exception. It is not a good thing for cats to be too obese. Obesity can cause some diseases in cats.

4. Severe hair loss. Cats that eat too much sweets are prone to hair loss. Cats’ bodies are intolerant to sugar, which is not conducive to hair growth.
