Do male cats have nipples? It is not easy to find nipples on cats due to their fur, but it is more obvious to think that female cats have nipples than male cats. What would they use it for?

Male cats have nipples like female cats. Typically, male cats can have 6 nipples, but this number can range between 6 to 10. Male and female cats are created with nipples in the womb. When the embryos develop, only female cats develop mammary glands to lactate future kittens.

Do male cats have nipples?


Mammals are vertebrate animals characterized by the presence of the mammary glands (amongst other things), which are used to produced milk for feeding their newborn babies. There is an average of 6400 species of mammals which include cats, dogs, and seals.

All mammals have mammary glands, and in some mammal groups, males and females have functioning mammary glands, but in this case, their mammary glands do not have nipples that include males and females.

Typically, only females can use their mammary glands to feed the newborn, which is true for cats. Male cats, like most mammals, do not use their nipples to lactate newborns.


Nipples on male cats can be more challenging to find since they are well hidden under the fur, and they are tiny. Female cats, especially if pregnant or if they have been pregnant, may have more pronounced and visible nipples.

Despite the difficulties in founding them, male cats have nipples on their bellies. They should have two parallel rows of nipples going down their belly or chest, with four nipples on each side. But, this number can vary from cat to cat. Some cats can have only 4 or 6 nipples or some other number.

It is not different than a female cat. In fact, a female cat typically presents eight nipples on two rows. But, even in the case of female cats, the number can vary. They can have five pairs, or three pairs, or even odd numbers.

Some people can think their male cat has only two nipples, but in that case, the rest of the nipples may be hard to find since they can be tiny.

But why do male cats have nipples if they are not supposed to raise kittens and feed them? After all, mama’s cat does everything.


Male cats have nipples because genetics wants that all mammals develop them at early stages in the fetus, even before sex is decided. When the fetus develops enough to become male or female, the bodies get built to enable a female to produce the milk when needed.

Hormones play a big part in milk production. Male cats do not get pregnant. Therefore their nipples never get stimulated by hormones to produce milk, even though they could. They have other types of hormones and body predisposition.

Why mother nature wants male to have nipples? Well, who knows if in the past males did nurse kittens, or they are supposed to do it in the future, or nature is just being too cautious and preparing for tough times.


Although male cats do not lactate and do not use their nipples, still they have them, and because of this, in some rare case, they can get infected or get other problems related to them.
