Actually, the reason men have nipples is because both males and females must carry enough DNA to reproduce humans of both genders. So both males and females have the stem cells needed for growing breasts. But since only females have ovaries, generally only maturing and adult females produce enough estrogen to cause their breasts to grow. Males can on occasion develop fully-mature breasts, and that's usually due to a hormone imbalance or due to medication.

∙ 15y agoThe term "supernumerary nipple" applies to individuals (as many as 1 in 50) who have an extra nipple, with or without an extra teat. Men are as likely as women to possess one, but it is often unnoticeably small.

Why do some people have hairy nipples?
Humans are still evolving, and because of that, some people have traits that have mostly disappeared by now, such as thick hair all over their bodies. Many species of mammals have more than two nipples, and it is possible that at some earlier time, proto humans had more than two nipples. Because humans very rarely have multiple births, more that two nipples are not necessary, so we are evolving away from that trait. That is my personal opinion, and I can not back it up with any factual evidence, so don't take it as a fact.

Is it possible to have nipples like a cat?
No. Have to look around the genital area. Ask a vet or another adult. The only way you could tell the sex of a cat by looking at the nipples would be if it is a nursing mother cat, in which case the breasts of the cat would be hanging lower and filled with milk. Otherwise a male cat's and a female cat's nipples look pretty much the same.
