Can a Cat Be in Heat While Pregnant?

Regarding feline reproductive matters, there are often many questions and misconceptions. One of the queries that frequently pops up in the world of cat owners is, “Can a cat be in heat while pregnant?” In this article, we will delve into this intriguing topic to shed light on the possibilities and complexities of feline reproduction.

Understanding the Feline Heat Cycle

Before we address the main question, let’s first understand the feline heat cycle. The heat cycle in cats, or estrus, is when a female cat is receptive to mating. This phase is characterized by various behavioral and physiological changes, including vocalization, restlessness, and rubbing against objects. During this time, the cat may attract male suitors.

The Stages of Feline Estrus

To understand whether a cat can be in heat while pregnant, we need to look at the stages of the feline estrus cycle:


Proestrus is the initial stage, lasting about a day or two. During this phase, the cat may exhibit mild behavioral changes but is not yet ready for mating.


Estrus is the most critical phase, typically lasting 4-10 days. This is when the cat is most receptive to mating. She may yowl, raise her hindquarters, and engage in mating behaviors.


Metestrus is a transitional phase, lasting a few days. The cat’s behavior returns to normal if mating doesn’t occur.


Anestrus is the final phase when the cat is no longer in heat. It can last several weeks to months before the next heat cycle begins.

Pregnancy in Cats

Now that we understand the feline heat cycle, we must grasp the concept of pregnancy in cats. Pregnancy in cats typically lasts around 63 to 65 days from conception to birth. During this time, a fertilized egg develops into a fetus.

Can a Cat Be in Heat While Pregnant?

The simple answer is no; a cat cannot be in heat while pregnant. When a female cat becomes pregnant, the hormonal changes suppress the heat cycle. Once conception occurs, the cat will no longer exhibit signs of estrus.

Why the Misconception?

So, why do some cat owners wonder if their cat is in heat while pregnant? There are a few reasons for this common misconception:

  1. Similar Behaviors: Some heat-associated behaviors, like increased vocalization or affection, can also be seen in pregnant cats. This similarity can lead to confusion.
  2. Incomplete Mating: In some cases, a female cat might have an incomplete mating, leading to the persistence of heat behaviors. However, this is rare.
  3. Pseudopregnancy: Sometimes, cats can experience pseudopregnancy, which mimics the signs of pregnancy and can lead to confusion. This condition can occur even without mating.

The Importance of Identifying Pregnancy

Recognizing whether a cat is pregnant or in heat is crucial for their care. Pregnant cats require special attention and care to ensure a healthy pregnancy and delivery.

Signs of Pregnancy in Cats

To determine if your cat is pregnant, watch for these signs:

  • Increased appetite
  • Weight gain
  • Nipple enlargement and color change
  • Abdominal enlargement
  • Nesting behavior


In conclusion, a cat cannot be in heat while pregnant. Once a female cat becomes pregnant, her heat cycle is suppressed, and she will not exhibit the typical behaviors associated with estrus. Understanding the differences between heat and pregnancy is essential for providing the best care to your feline companion during this critical time.


Indeed, here are answers to the “People also ask” questions:

Will my cat still be in heat if she’s pregnant?

No, if your cat is pregnant, she will not be in heat. Pregnancy in cats suppresses the heat cycle, so once conception occurs, the cat will not exhibit signs of estrus.

Why is my pregnant cat acting like she’s in heat?

Pregnant cats may exhibit behaviors similar to being in heat due to hormonal changes and pseudopregnancy. Pseudopregnancy can mimic heat behaviors and is not uncommon in pregnant cats.

How do I know if my cat got pregnant during the heat?

Determining if your cat got pregnant during heat can be challenging without professional veterinary assistance. Signs of pregnancy, such as weight gain, nipple enlargement, and nesting behavior, become more evident as the pregnancy progresses.

What are the signs of cat pregnancy?

Cat pregnancy signs include increased appetite, weight gain, nipple enlargement, abdominal enlargement, and nesting behavior. A veterinarian can confirm pregnancy through physical examination or ultrasound.

How many months is a cat pregnant for?

Cats are pregnant for approximately 63 to 65 days, roughly two months.

What not to do when your cat is pregnant?

When your cat is pregnant, avoid exposing her to stressful situations, providing an inadequate diet, or allowing access to potentially harmful substances. It’s essential to consult with a veterinarian for proper care.

What does a 7-week pregnant cat look like?

At 7 weeks of pregnancy, a cat may show slight abdominal enlargement, but it might not be highly noticeable. The most reliable way to confirm pregnancy is through a veterinarian’s examination.

What do female cats do when they’re pregnant?

Pregnant female cats may exhibit increased appetite, weight gain, nipple enlargement, and nesting behavior as they prepare for the birth of their kittens. It’s essential to provide them with a quiet and comfortable space for delivery.
