When brushing a cat’s teeth, pet owners first need to buy a cat-specific toothbrush and toothpaste. This toothpaste can be eaten by cats (it is best not to eat it). Before brushing teeth, it is best to wrap the cat's limbs and feet with a towel to prevent the cat from scratching. Then squeeze a little toothpaste to let the cat taste the taste and get used to it, then open the mouth and brush gently from top to bottom. That's it. Be careful to only brush the outer area when brushing your cat's teeth, because most cats will not accept you moving the brush into the mouth to clean the back. Also be careful not to hurt the cat's gums. You can give the cat a reward appropriately after brushing the teeth. After a period of time, the cat will gradually adapt to it and no longer need to wrap it in a towel.
