Can cats eat sugar?

Cats can eat sugar, but it is not recommended to feed them too much. If there is too much sugar in their diet, cats will be unable to absorb it, which can cause harm to their bodies and impact their health. Therefore, if your cat is just curious about the taste of candy, you can let them lick it. Additionally, some types of sugar can cause poisoning in cats, such as those containing alcohol or chocolate. It is advised to avoid feeding cats human food randomly, and to prioritize cat food in their diet.

Here are the specific reasons:

Sugar is sticky and easily remains in a cat's mouth. If the owner does not brush the cat's teeth regularly, bacteria can easily breed, leading to dental problems like cavities, tartar, or periodontal disease, which threaten the cat's oral health.
Because sugar-rich foods have a high sugar content, long-term consumption of large amounts of sugar can cause obesity in cats. This can lead to secondary diseases such as diabetes and heart disease, and in severe cases, even kidney failure.
Cats have limited digestion and absorption capabilities for sugar. Excessive consumption of sugar can cause diarrhea in cats.
Some sugar particles are large and if a cat accidentally swallows them, they may get lodged in the throat, causing obstructions in the esophagus.
