If a cat sheds tears while eating, it may be caused by the salty food, the cat bowl being too low, foreign matter in the nasal cavity, or the smell of cat food being pungent. The specific cause needs to be determined based on the cat's condition. Do not feed your cat food that is too salty, otherwise the cat will easily get angry and shed tears. Also, the cat bowl should not be placed too low, as the cat’s tear ducts may be oppressed when eating.
