Observing alterations in your cat’s behavior and physique? Pregnancy might be the cause. Cats can conceive as early as four months old and continue throughout their lives. As a responsible cat owner, recognizing the signs of feline pregnancy is crucial. These signs include swollen nipples, an expanding abdomen, appetite changes, weight gain, vomiting, and nesting behaviors. If you suspect pregnancy, consulting a veterinarian is essential. They can diagnose it through methods like physical examination, palpation, ultrasound, radiographs, or pregnancy tests. Being aware and taking suitable actions, such as early spaying, not only prevents unwanted pregnancies but also ensures your cat’s health and well-being.

Signs of Pregnancy in Cats

A pregnant cat will experience physical and personality changes within a few weeks of mating. It is important to be aware of these signs in order to provide the necessary care and support during this time. Some common signs of pregnancy in cats include:

Swollen Nipples

One of the earliest signs of pregnancy in cats is swollen nipples. The nipples will become enlarged and may appear pink or reddish in color. This is due to the increase in hormones and the preparation of the mammary glands for milk production.

Enlarging Abdomen

As the pregnancy progresses, you may notice your cat’s abdomen getting larger. This is a result of the growing kittens inside. The abdomen will become round and firm to accommodate the developing fetuses. It is important to monitor the size of the abdomen to ensure the kittens are growing properly.

Change in Appetite

During pregnancy, a cat’s appetite may change. Some cats may experience an increase in appetite, while others may lose interest in food. It is important to provide a balanced and nutritious diet to support the mother cat’s health and the development of the kittens. If you notice any significant changes in appetite, it is best to consult with a veterinarian.

Weight Gain

Due to the growing fetuses and increased fluid retention, pregnant cats will often gain weight. The weight gain may be gradual, and it is important to monitor the cat’s overall body condition to ensure a healthy pregnancy. It is not uncommon for pregnant cats to gain 2-4 pounds during pregnancy.


Morning sickness can occur in pregnant cats, just as it does in humans. Some cats may experience occasional vomiting or nausea during the early stages of pregnancy. This is usually temporary and not a cause for concern unless it becomes persistent or severe.

Nesting Behaviors

As the due date approaches, you may notice your pregnant cat exhibiting nesting behaviors. She may start seeking out quiet and secluded areas to create a comfortable space for giving birth. This can include scratching or kneading bedding materials, rearranging blankets, or seeking out confined spaces. Providing a cozy and safe nesting area can help alleviate any stress or anxiety your cat may be experiencing.

Diagnosing Pregnancy in Cats

It is important to confirm a cat’s pregnancy to ensure proper care and preparation. Veterinarians can use a variety of methods to diagnose pregnancy, including:

Physical Examination

During a physical examination, a veterinarian will carefully feel and examine your cat’s abdomen. They may be able to detect the presence of developing kittens by feeling for the enlargement of the uterus or the presence of fetal structures.


Palpation is a technique where the veterinarian uses their hands to feel for the presence of developing fetuses. This method is typically done around three to four weeks after mating, when the kittens are large enough to be felt.


Ultrasound is a non-invasive imaging technique that can provide real-time images of the uterus and developing fetuses. This method can be used as early as 21 days after mating to confirm pregnancy and assess the number of kittens.


Radiographs, or X-rays, can be used later in the pregnancy to obtain images of the kittens’ skeletons. This method is typically done around 45 days after mating and can help determine the number of kittens and their position within the uterus.

Pregnancy Tests

Similar to human pregnancy tests, there are also pregnancy tests available for cats. These tests detect the presence of a hormone called relaxin, which is produced by the developing placenta. However, it is important to note that these tests may not always be accurate, especially in the early stages of pregnancy.

Stages of Labor in Cats

Understanding the different stages of labor in cats is essential for providing the necessary support and care during the birthing process. The stages of labor in cats can be divided into two main stages:

First Stage: Contractions and Cervix Opening

The first stage of labor in cats is characterized by contractions and the opening of the cervix. During this stage, the cat may appear restless, pace, or exhibit nesting behaviors. The contractions become more frequent and stronger as labor progresses. This stage can last several hours, and it is important to provide a calm and quiet environment for the cat.

Second Stage: Delivery of Kittens

The second stage of labor is when the actual delivery of the kittens occurs. The cat will typically assume a squatting position and begin pushing. The kittens will be delivered one at a time, with some time in between each delivery. The mother cat will usually break the amniotic sac and clean the kittens by licking them. It is crucial to allow the mother to bond with her kittens and provide assistance only if necessary.

Signs of Impending Birth in Cats

As the due date approaches, there are several signs that indicate a cat is about to give birth. These signs include:

Nesting Activities

You may notice your pregnant cat becoming increasingly focused on creating a safe and comfortable nesting area. She may start exploring different areas and rearranging bedding materials to create a suitable environment for giving birth.


Restlessness is a common sign that labor is approaching. Your cat may seem unable to settle, continually moving around, and searching for a suitable place to give birth. This restlessness is a natural instinct and indicates that the cat is preparing for the imminent arrival of her kittens.


As labor approaches, some cats may start panting. Panting helps regulate the cat’s body temperature and aids in the oxygen supply needed during the intense labor process. If you notice excessive panting or signs of distress, it is important to seek veterinary assistance.


Some cats may vocalize during labor to communicate their discomfort or ask for assistance. These vocalizations can range from low growls to high-pitched cries. It is essential to remain calm and provide reassurance to your cat during this time.

Lowered Body Temperature

A significant drop in body temperature, often below 100 degrees Fahrenheit, is a common sign that labor is imminent. It is recommended to monitor your cat’s temperature regularly in the days leading up to the due date to anticipate the arrival of the kittens.

Loss of Appetite

As labor approaches, your cat’s appetite may decrease or even disappear completely. This is a normal part of the birthing process and is due to the hormonal changes and the focus on labor and delivery. However, it is crucial to ensure your cat remains hydrated, as dehydration can pose risks during labor.

Vulva Licking

During labor, your cat may lick her vulva excessively. This grooming behavior helps stimulate contractions and aids in the delivery process. It is crucial to allow your cat to carry out this instinctual behavior without interruption.

Caring for Newborn Kittens

Cat mothers are usually equipped with natural maternal instincts and are capable of caring for their newborn kittens without intervention. However, there are a few aspects to consider to ensure the health and well-being of the kittens:

Cat Mothers’ Natural Ability

Most mother cats instinctively know how to care for their kittens. They will nurse the kittens, clean them, and provide the warmth and comfort they need. It is essential to provide a quiet and stress-free environment for the mother and her kittens, allowing her to carry out her maternal duties undisturbed.

Contacting a Veterinarian for Help

While cat mothers typically do well caring for their kittens, there may be instances where intervention or assistance is required. If you notice the mother displaying signs of distress, aggression towards the kittens, or if the kittens are not nursing adequately, it is important to contact a veterinarian for guidance and assistance. They can provide advice and recommendations based on the specific situation.

Preventing Unwanted Pregnancies

Given that cats can become pregnant as young as four months old and continue to go into heat, become pregnant, and give birth throughout their entire lives, it is vital to take measures to prevent unwanted pregnancies. Early spaying is the most effective method to prevent pregnancy in cats. By spaying a female cat before her first heat cycle, the risk of unplanned pregnancies, certain cancers, and other reproductive issues is significantly reduced. Spaying not only benefits the individual cat but also contributes to reducing the stray and feral cat population.

In conclusion, being aware of the signs of pregnancy in cats, understanding the stages of labor, recognizing the signs of impending birth, and providing appropriate care and support are essential for ensuring the health and well-being of both the mother cat and her kittens. If you have any concerns or questions regarding your cat’s pregnancy or the birthing process, it is always best to consult with a veterinarian.

Signs of pregnancy in cats include swollen nipples, enlarging abdomen, change in appetite, weight gain, vomiting, and nesting behaviors.
