However, it should be noted that not all white cats with black hair on their heads can be classified as "Indian star cats". This is just an informal name, and there is no clear scientific classification. White cats are common in many breeds, and some breeds may have black "marks", but this does not mean that they are all the same breed.
If you really want to know the true breed of your pet cat, the best way is to consult a professional pet doctor or breeder. They can judge the breed of cats according to their coat color, body shape and behavior, and provide corresponding maintenance suggestions.
No matter what breed your pet cat is, make sure it gets proper food and medical treatment to ensure its health and happiness. White cats with black hair on their heads do not affect their health and happiness, which is just a feature of their appearance.
