You shouldn't use human shampoo on your cat. Human bathing products are designed primarily for the physiological characteristics of human skin and are not suitable for cats. You must use pet-specific shampoo because human shampoo contains certain ingredients or fragrances that can cause discomfort in cats.

Secondly, unlike humans, cats do not have sweat glands on their skin. Their skin does not have sweat glands. Instead, their unique subcutaneous tissue secretes a substance that makes their fur shiny and waterproof. Using improper shampoo can damage this tissue and harm their fur. Therefore, you should not use human shampoo to bathe your cat.
