CATDOLL : What causes black chin cats?

The main reasons for cats' black chins are long-term use of plastic bowls, endocrine disorders, eating too oily cat food, dirty living environment, and clogged hair follicles.

Generally speaking, plastic bowls are very easy to breed bacteria, so once we use them for cats, it is very easy for cats to have black chins. Secondly, when cats reach sexual maturity, their endocrine system will be out of balance, which will gradually cause them to have black chins. Finally, if we usually feed cats with too much oily cat food or the living environment is dirty and the daily cleaning is not done well, causing the hair follicles to be blocked, this situation will also occur.
