Reasons why cats won't eat cat food. There are two main reasons: pathological factors and physiological factors.
1. One possibility is pathological factors, which are mainly related to gastrointestinal diseases. In this case, it is recommended that the cat owner take the cat to a veterinary hospital for treatment and medication.
2. One reason is physiological factors. Physiological factors include the cat food becoming spoiled or the taste of the cat food not being suitable for the cat's palate. Cats that refuse to eat cat food due to physiological factors do not require medication, but cat owners should adjust the cat food in a timely manner. 
What kind of cat food is best for cats?
When choosing cat food, try to avoid cheap cat food that is high in salt and oil, such as loose, low-quality cat food. Although it is cheap, it can harm your cat's kidneys. It is recommended to choose natural, low-salt, organic cat food, which contains more real meat and has a more balanced combination of vegetables and other ingredients. When purchasing, you can check the ingredient list for peace of mind.
