Why is My Cat Stomach Still Big After Giving Birth? [Comprehensive Guide]

why is my cat stomach still big after giving birth

Have you ever noticed your cat’s stomach remaining big even after giving birth? It’s a common concern among cat owners, but don’t worry; we’ve got you covered.

This article explores the reasons behind this phenomenon and provides solutions to help your feline friend return to normal.

Understanding Cat Pregnancy and Postpartum Changes

The Cat Pregnancy Process

Like humans, cats undergo a pregnancy process that lasts approximately 63-65 days. Their bodies undergo significant changes during this time to accommodate the growing kittens.

They gain weight, and their bellies expand. But what happens after they give birth?

Physical Changes in Cats After Giving Birth

After giving birth, it’s normal for a cat’s body to change. Their bellies may remain enlarged for a while due to the stretched skin and muscles.

This is similar to what happens in human mothers postpartum. However, if the belly doesn’t shrink to its normal size after a few weeks, it could be a sign of a problem.

Hormonal Changes in Cats After Giving Birth

Just like physical changes, hormonal changes are also a part of the postpartum process. Hormones high during pregnancy, such as progesterone and estrogen, decrease after birth.

This hormonal shift can change behavior and physical appearance, including belly size.

Common Reasons for a Big Stomach After Birth

Normal Weight Gain

It’s normal for cats to gain weight during pregnancy and retain some of it after giving birth. This weight can contribute to a bigger belly.

However, if the belly remains significantly large for an extended period, it could indicate other issues.

Retained Kittens or Placenta

Sometimes, not all kittens or placentas are expelled during birth. If a kitten or placenta is retained, it can cause the mother’s belly to remain big. This condition is serious and requires immediate veterinary attention.

Postpartum Swelling

After giving birth, a cat’s uterus may remain enlarged for a few days, causing the belly to appear bigger. This is usually normal and should resolve on its own.

False Pregnancy

In rare cases, cats can experience a false pregnancy where their body behaves as if it’s pregnant when it’s not. This can lead to weight gain and a bigger belly.

Postpartum Edema

Edema is a condition characterized by an excess of watery fluid collecting in the cavities or tissues of the body. Postpartum edema can occur in cats, leading to a swollen belly.

Postpartum Metritis

Metritis is an inflammation of the uterus that can occur after birth. It can cause the belly to appear larger and is often accompanied by other symptoms such as fever, lethargy, and decreased appetite.

Health Concerns Related to Big Stomach After Birth


Pyometra is a serious and life-threatening condition that can occur in unspayed female cats. It’s characterized by a pus-filled uterus, and one of its symptoms can be an enlarged abdomen.

Mammary Gland Hyperplasia

This condition is where the mammary glands enlarge, leading to a bigger belly. It’s often hormone-related and can occur after giving birth.


Obesity is a common health concern in cats and can contribute to a big belly. If your cat is overweight, addressing this issue is important as it can lead to other health problems.

Feline Infectious Peritonitis (FIP)

FIP is a viral cat disease that can cause fluid accumulation in the abdomen, making it appear larger. It’s a serious condition that requires veterinary attention.

Ascites in Cats

Ascites are the accumulation of fluid in the abdominal cavity, which can cause the belly to enlarge. It can be a symptom of several health issues, including heart disease, liver disease, or a ruptured bladder.
