This is the cat protecting its food. When the cat is eating, it will make this sound out of instinct to warn other creatures not to get close. Parents should not disturb the cat's eating at this time to prevent it from accidentally hurting you. If there are multiple cats in the household, it is best for parents to feed them separately, which can avoid many problems.

Tip:

Cats are pure carnivores. We should choose cat food with as much meat as possible. If parents have the conditions, they can also make their own cat food.
