Yes, male cats have nipples, just like female cats do.
They don’t produce milk and have no function in males, but because nipples form before male and female embryos diverge in development, both sexes are born with them.
What Do Male Cat Nipples Look Like?
Male cat nipples are small, round bumps that lie flat against the skin, and they look the same as those of a non-pregnant female cat. They are usually pink or close to the color of the surrounding skin and may appear darker on cats with darker skin.
To find them, gently run your hand along your cat’s belly from the chest toward the groin. The nipples are arranged in two rows, though they may not line up perfectly. On longhaired cats, you may need to part the fur to see them.
Nipples can sometimes be mistaken for ticks or skin tags. A nipple is smooth and part of the skin itself. Skin tags tend to stick out or hang from the skin, while ticks sit on top of it and may feel harder or rougher.
How Many Nipples Do Male Cats Have?
Male cats can have anywhere from four to ten nipples, with six or eight being most common. Odd numbers such as seven or nine are less common but still normal.
The exact number varies from cat to cat and can differ between kittens from the same litter.
Why Do Male Cats Have Nipples?
It comes down to how kittens develop in the womb. Early on, male and female kittens develop the same way, and nipples form during that shared stage. Sex-based differences only appear later.
By then, the nipples are already there. In female kittens, the tissue behind them develops into mammary glands that can produce milk. In male kittens, that tissue stays underdeveloped, so the nipples remain but never become functional.
Can Male Cats Get Nipple or Mammary Problems?
Mammary tumors are rare in male cats, accounting for roughly 1% to 5% of feline mammary tumor cases. They often appear as a small, firm lump beneath or beside a nipple and may grow larger or become ulcerated over time.
A swollen or painful area around a nipple can also be caused by an infected bite, scratch, or other wound. These infections may cause redness, warmth, swelling, pain, or discharge.
Any new lump, persistent swelling or redness, discharge, or open sore around a nipple should be checked by a vet.
FAQ
Do Male Cats Have Nipples?
Yes. All male cats are born with nipples.
How Many Nipples Do Male Cats Have?
Most male cats have six or eight nipples, although anywhere from four to ten can be normal. Odd numbers can occur too.
Why Do Male Cats Have Nipples If They Can’t Produce Milk?
Nipples form early in development, before male and female kittens diverge, so both sexes are born with them. In males, the mammary tissue never develops into milk-producing glands.
Can You Tell a Cat’s Sex by Their Nipples?
No. Male and female cats both have nipples, and they generally look the same unless a female is pregnant or nursing.
Do Male Cats Have Teats?
Yes. Teats and nipples are two words for the same structure. “Teat” is more commonly used for livestock, while “nipple” is the term you’re more likely to hear for cats.
Can Male Cats Get Breast Cancer?
Yes, but it is rare. Male cats can develop mammary tumors, so any new lump beneath or around a nipple should be checked by a vet.
