The ten taboos of bathing cats are: do not bathe your cat too frequently; do not bathe your cat in cold and damp weather; do not bathe your cat while it is sick; kittens under six months old should not be bathed frequently; do not bathe your cat within two weeks after vaccination; do not bathe your cat too often; avoid excessive resistance; and pay attention to the water temperature.

When cats groom themselves, they lick their fur to remove dirt. If you use bath water containing human shampoo, the cat may swallow the shampoo residue, leading to indigestion or poisoning.
Cats have their own unique scent, which is very important for their socialization and identity. Using human shampoo to wash a cat's fur will destroy its natural scent, making it difficult for the cat to interact with other cats and its environment.
