Cats are not allowed to dye their hair. Do not dye their hair when raising cats at home, because cats have the habit of licking their hair. When cats lick dyed hair, it will cause the cat's body to push toxins, which will cause long-term consequences. Cat poisoning can seriously damage the cat's internal organs and cause death. Furthermore, human hair dye products contain a variety of additives and are not suitable for cats and other pets.
