Yes. Male cats have nipples. They are a normal part of feline anatomy, usually arranged in two rows from the chest toward the underside of the abdomen. In males, the mammary tissue normally remains small and does not produce milk. A tiny, stable nipple is ordinary; a new lump, swelling, discharge, redness, crusting, ulceration or other change should be assessed by a veterinarian.
Why male cats have nipples
Nipples begin forming while a kitten is still an embryo, before its sex has been fully determined. The basic mammary structures therefore develop in both male and female cats. Later, hormones stimulate much more development in females, allowing mammary glands to support nursing. In males, the structures generally remain small and non-functioning.

This is why finding small bumps on a boy cat’s belly does not mean the cat is female, intersex or unwell. Cats Protection describes male nipples as normal, non-functioning anatomy. Their presence also does not depend on whether a cat has been neutered.

Most feline nipples lie in two roughly parallel rows. They start around the chest and continue down the underside of the abdomen. The rows are not always perfectly straight or symmetrical, and a nipple can be slightly offset from the one on the opposite side.

They may be easiest to see on a short-haired cat or feel when the cat is relaxed. On a long-haired cat, you may need to part the fur gently. A normal nipple is usually a small, discrete bump in the skin rather than a broad, deep swelling beneath it.
How many nipples do cats have?
There is no single number that every cat must have. Cats Protection reports an average of around six to eight nipples, while individual cats may have more or fewer. Merck Veterinary Manual describes four pairs of mammary glands in cats, which corresponds to eight gland positions in the typical arrangement. Those figures describe normal anatomy at a population level, not a pass-or-fail count for an individual pet.
| What is being counted | What veterinary references report | How to interpret it |
|---|---|---|
| Visible or palpable nipples | Cats average around six to eight, with individual variation (Cats Protection, 2023) | A cat can normally have fewer or more than the average. |
| Mammary gland pairs | Four pairs are described in cats (Merck Veterinary Manual, 2024) | Gland positions are a useful anatomical description, not a guarantee that every nipple will look identical. |
| Left-to-right appearance | Rows need not be perfectly symmetrical | A small difference in position or spacing is not automatically a problem. |
Counting is not a reliable way to judge health. If you find only five, seven or another number, do not try to “correct” the count or assume the cat’s sex has been misidentified. Focus instead on whether a particular spot is new, changing or associated with other signs.

A normal nipple is typically small, close to the skin and relatively stable over time. It may be easier to feel than to see, especially under dense fur. The surrounding skin should not be persistently hot, markedly red, crusted, ulcerated or leaking fluid.
Normal nipples can vary in size, pigmentation and spacing. One may be easier to find than another. A cat may also tense its abdominal muscles or object to handling, making a normal structure temporarily harder to assess. Compare the area gently with the same location on the other side, but do not press hard or repeatedly manipulate it.
When a nipple or nearby lump needs veterinary attention
Contact a veterinarian if you notice a change rather than relying on appearance alone to identify the cause. Cats Protection advises an examination for changes in size or color, swelling, discharge, lumps, redness or crusting. The American College of Veterinary Surgeons (ACVS) also lists a palpable mass near a nipple, discharge, ulceration and painful swelling among signs that can occur with mammary tumors.
- A bump that is new, enlarging, firm or fixed beneath the skin
- Swelling that extends beyond the tiny nipple itself
- Redness, heat, persistent irritation or obvious pain
- Clear, bloody, milky or otherwise abnormal discharge
- Crusting, an open sore or ulceration
- A change in color or shape that does not settle
These signs do not prove cancer. They indicate that a hands-on examination is needed. A veterinarian may need to feel the entire mammary chain and surrounding tissues and decide whether further testing is appropriate. Do not squeeze a lump or attempt to drain discharge; that can hurt the cat and may complicate assessment.

Yes, although mammary tumors are uncommon in male cats. Merck Veterinary Manual notes that feline mammary tumors are particularly prevalent in intact females and that exposure to progestins can contribute in both sexes. ACVS describes mammary tumors in male cats as rare, not impossible.
Merck reports that approximately 80%–90% of mammary tumors in cats are malignant. That statistic applies to feline mammary tumors overall; it is not a male-specific risk estimate. Because a rare condition can still occur, a new mass near a male cat’s nipple should not be dismissed simply because he is male.
A tumor cannot be confirmed or excluded by looking at a bump. Size, firmness, mobility, skin appearance and the cat’s general health may guide a veterinary work-up, but none is a do-it-yourself diagnostic test. Arrange an appointment promptly for any persistent or progressive change, and seek urgent advice if the cat has severe pain, an open ulcer or appears acutely unwell.
How to check your cat without hurting him
- Choose a calm moment. Check when your cat is relaxed, such as after resting. Stop if he becomes distressed.
- Part the fur gently. Use your fingers rather than pulling with a brush or tool. Look for the two rows from chest to abdomen.
- Use light fingertip pressure. Identify small, skin-level nipples and note their approximate locations. Do not pinch, squeeze or try to express fluid.
- Compare the surrounding area. Notice whether one site is substantially larger, hotter, redder, harder or more painful than the others.
- Record a change. A dated photograph or brief note can help your veterinarian understand when a difference began, but do not delay care while monitoring it.
- Book veterinary advice when anything is abnormal. Describe the location, how long it has been present and whether it is changing or producing discharge.
Routine handling should be gentle and occasional. Repeatedly poking a normal nipple can irritate the skin and make it harder to tell what was present originally.
Common misunderstandings
“Nipples mean my cat is female.”
No. Both sexes develop nipples before the later hormonal differences that affect mammary development. Nipples cannot be used to sex a kitten or adult cat.
“A male cat should have no mammary tissue.”
Male cats retain mammary structures, but they normally do not develop the milk-producing function seen in females. Small nipples are therefore expected.
“Every cat must have exactly eight.”
No. Four pairs are a standard anatomical description, while Cats Protection notes an average of six to eight nipples and individual variation. Missing a nipple during a visual check is not proof that anything is wrong.
“Any bump beside a nipple is just the nipple.”
A tiny, stable nipple and a new or enlarging lump are not the same finding. If you cannot tell which you are feeling, let a veterinarian examine it rather than trying to diagnose it at home.
What information to give the veterinarian
Before the appointment, note which side and body area are involved, when you first noticed the change and whether it has grown. Record discharge, redness, crusting, pain or changes in appetite and behavior. Tell the clinic about medications and any known exposure to hormone-based treatments, because Merck identifies progestin exposure as a factor that can contribute to mammary tumors in both sexes.
Do not assume that a normal appetite or playful behavior rules out a local mammary problem. Conversely, do not assume that a mass is malignant from its appearance. The examination and any tests your veterinarian recommends are what distinguish normal anatomy from disease.
Bottom line for owners
Male cats have nipples because mammary structures form early in development in both sexes. Most are small, non-functioning and arranged in two rows; six to eight is a commonly reported average, but counts and spacing vary. Leave a stable, tiny nipple alone, and seek veterinary advice for a new or changing lump, swelling, discharge, redness, crusting, ulceration or painful area.
