Pregnant Cat Nipples vs Normal: Vet-Verified Differences Explained

Both male and female cats have nipples, but the female’s nipples will change during and after pregnancy to accommodate the nutritional needs of her little ones. After all, those nipples must be ready to feed several kittens at the same time. Changes in a female’s nipples can be a big sign that she has become pregnant, so it’s a good idea to know the differences between normal and pregnant cat nipples.

Understanding the differences will make it easier to determine when a cat is pregnant. Even if you know a cat is pregnant before her nipples start to change, you should know what nipple changes to expect so you can seek help if something looks off at any time during the pregnancy.

Here is everything that you need to know about the differences between normal and pregnant cat nipples.

Overview of Normal Cat Nipples

Cats have several nipples located along their bellies. There are typically six to eight nipples in all, situated in pairs. Occasionally, a cat might have more or fewer pairs of nipples or an odd number of nipples altogether. What’s interesting is that both male and female felines have nipples laid out in this way.So, you cannot tell whether it’s a male or female just by looking at a cat’s nipples.

How Cat Nipples Work

Every nipple on a male or female cat is connected to a dedicated mammary gland, which is what produces milk when the need arises, which should only be when a female gets pregnant. Each mammary gland is connected to a small duct that delivers milk through a canal that releases the milk out of the nipple. Milk production only takes place when pregnancy occurs, unless a health problem develops.

When a cat is not pregnant, their nipples are small and firm. They are not typically apparent unless you look for them. Sometimes a little bare skin shows around each nipple, but in many cases, all that protrudes from the fur is the small nipple that looks like a wart. If a cat’s fur is long and thick, one may have to feel for the nipples because they are so hidden.

About Male Cat Nipples

Male cats have nipples just like female cats do because they develop before sex anatomy is established in the womb. However, their nipples have no function once hormone changes result in the development of male anatomy. A male cat’s nipples do not go through any changes during their lifetimes. They stay small and hard, and they are often hard to spot with the human eye. Male cats can get mammary cancer and so any changes should be checked by a vet promptly.

You may start to notice a pregnant cat’s nipples change after just a few weeks. These changes happen to prepare the nipples for nursing once the kittens are born. The nipples do not just change one time or in one way throughout pregnancy. Changes can be noticed twice during pregnancy and once again after giving birth.

Nipple Changes in Early Pregnancy

It takes about 2–3 weeks of pregnancy for nipple changes to start occurring. At this time, the nipples do what is referred to as “pink up,” which means that they get larger and become redder in color. At this point, the nipples should be more noticeable because they usually double in size. The surrounding tissue of the pregnant cat’s nipples becomes exposed from the fur and is usually pink and looks inflamed. There should be no discharge happening at this point of pregnancy.

Nipple Changes in Late Pregnancy

By late pregnancy, a pregnant cat’s nipples have already enlarged to the size that they will stay until the feline gives birth. However, the area around the nipples will enlarge and become more prominent. About 2 weeks before the kittens are born, it is common to see a little discharge coming from the mom’s nipples. The discharge is typically milky or clear and can be continuous or sporadic depending on many factors, including gestation period and health status.

Nipple Changes After Pregnancy

After giving birth to her kittens, a female cat produces milk to nurse her kittens. This stimulation will make the nipples even larger and look full. The nipples may hang down as the mother walks because she is carrying so much milk. The nipples stay swollen and red or pink throughout the nursing period. Once the kittens begin weaning off their mother’s milk, the mother’s nipples slowly start to shrink and look normal again.

However, some female cats’ nipples never shrink back to the size that they were before giving birth. They will stay slightly enlarged and easier to see.
