Symptoms experienced by a pregnant bitch or cat

Fortunately, every time we take better care of our pets. They live at home with us, we care about their diet, their daily exercise, their hobbies and, of course, their health. Within this terrain and when they are females that are not spayed or neutered, there is a possibility that they may be pregnant. Under this premise, let’s see the signs that our pets are leaving so that we know its status in the two quintessential domestic animals: bitches and cats.


Pregnancy of a cat lasts about 63 days. In the first few weeks, there are usually no external changes. However, once these start to surface, you will notice them. When i’m three weeks, you should experience some noticeable changes in behavior and physical appearance.

Dark nipples

Around three weeks, a pregnant cat’s nipples will darken and enlarge. You may also notice a milky discharge from the nipples, although cats don’t start producing milk until after birth.

Morning sickness

Like humans, a pregnant cat can also go through a period of illness. Not all cats have morning sickness, but if you do, keep an eye on her and discuss it with your vet if vomiting becomes frequent or if the animal suffers a general malaise.

Swollen belly

At 30 days, pregnant cats begin to develop a rounded and swollen abdomen, a signal that is not always so easy to detect. A pregnant cat you will gain one to two kilos in total, depending on the number of kittens.


With only two weeks of pregnancy left, a pregnant cat can begin to nest. You can choose a quiet place and start organizing blankets to create a birthing area. Your pet can also act more motherly, be more affectionate with you and purr more often. At the same time, it could become less tolerant of other animals.

Positive ultrasound

The best way to know if your cat is pregnant is visit the vet and get an x-ray or ultrasound. X-rays do not show kittens until 40-45 days, when skeletons are visible. For its part, ultrasounds can be performed from 21 days, but often it is difficult to count the number of kittens with an ultrasound, compared to x-rays.


The gestation periods of bitches are relatively short: 56 to 70 days, very similar to that of cats. As a result, act quickly at the first signs of pregnancy is crucial to ensure a comfortable and safe delivery. After a proper examination, your vet can provide you with all the instructions you need to properly care for your pregnant dog.

Decrease activity

If your bitch runs out easily or spends more time sleeping, it may mean that she is pregnant. For bitches who are usually very active, this change should be taken seriously. On the other hand, for those who enjoy sleeping all day, it may be more difficult to notice the lack of energy. If this is the case, please try to pay more attention to how quickly you tire during walks.

Changes in appetite

A pregnant bitch’s appetite can fluctuate in different ways, depending on the animal and the stage of her pregnancy. In the first weeks or mid-gestation, you can eat less or even vomit occasionally (the canine equivalent of morning sickness). However, you can also eat more than usual and be dissatisfied with your meals. These fluctuations correspond to changing hormones.

Unusual behavior

You can notice certain changes in their behavior. For example, the bitch can seek the affection of its owner more often. A pregnant dog may spend more time with you, wanting additional attention. On the other hand, you may seek isolation, appear depressed, or even irritable when paid attention to.

Enlarged or discolored nipples

While a bitch’s nipples are normally small, pregnancy causes them to grow in size during the early stages. The areolas also become somewhat rounded, compared to its usual size and shape. You may also notice that the nipples become a little darker, indicating an increase in blood flow. Later in pregnancy, your nipples may even leak milk.

Weight gain and a bloated abdomen

As the cubs grow, your bitch’s abdomen will expand. This can be one of the clearest indicators of a bitch’s pregnancy, especially if there is no other reason for a sudden weight gain. However, an enlarged abdomen occurs relatively late, which means if you notice it, it’s time to take her to the vet.


As we explained earlier with cats, during the last weeks of pregnancy, you may notice that your dog begins to pile clothes and other materials available to create a birthing zone. Also may become irritable and lonely during this time, so it is best to limit your contact with young children.
