Why does my cat bleed from the vulva?


During the first weeks, you will not notice any significant change in your body, but after the first three weeks you will see some signs that will indicate that you are waiting for kittens.

When you find that she is pregnant, go to the vet to confirm it. He will advise you what steps you should take until the time of delivery arrives.


- Their breasts increase in size and turn pink.

- Manifests discomfort and even morning sickness.

- Increase weight gradually, one or two kilos depending on the number of kittens you are brewing.

- Her belly begins to swell, but she avoids touching it so as not to harm the fetuses.

- Begins to manifest "maternal" behaviors, basically purrs in excess.

- Show concern and avoid eating.

- Your cat is looking for a quiet place where childbirth can develop.

Before the first symptom of childbirth, which is manifested by a temperature drop to about 37.8 ° C, contact the veterinarian. You will immediately appreciate how your abdomen contracts, and your cat gives off vaginal discharge.


During the first half of pregnancy - until about 30 days - developing fetuses will not demand too much from their future mother. However, after the fourth week, things will begin to change, and the pregnant cat will need you to help her through this period of physical stress.

To do this, you must increase the contribution of protein and calories in your diet, about 15% per week, from the fifth week of gestation. What we recommend is that you change your usual dry food variety for another, whose level of essential nutrients is higher, and meets your needs during the process. A special kitty food will help cover all this extra demand.

Fortunately, pregnant cats eat reasonably. As long as you offer a sufficient amount of food, she will adapt her daily intake to her needs. Do not worry too much if you gain weight.Your food consumption will increase, especially during the last 20 days. Typically, you gain 40% weight during the entire gestation process.


Ideally, the veterinarian has provided your cat with booster shots just before breeding. During the first days of breastfeeding, cats in good health transmit their immunity to kittens, so it is important to make sure that your cat's antibodies are at their highest level.

In any case, it is convenient to avoid giving medications to cats during pregnancy, due to the counterproductive effect on the formation of fetuses. The only exceptions are associated with the presence of certain parasites. In these cases, turn to the veterinarian to offer you the best solution.


It is rare for complications to occur during pregnancy. However, when your cat is in gestation or about to give birth, it is important that you keep in mind that there are precursor signs that can guide you towards possible complications that you should monitor.

Vaginal blood losses during pregnancy should not be considered as a normal factor. If your cat is at risk of losing her little ones when she is about 8 weeks old, she may go into labor prematurely and need a C-section. That is an indispensable reason to go to the veterinarian.

Do cats bleed during heat?

There are still many people who wonder if cats have the period, as they tend to compare the cycle with dogs, which do bleed when they are in heat. Dogs and cats may be similar in some ways, but they are different species with big differences, and this is one of them.

There are two types of pyrethrum: closed, in which pus is not expelled and the uterus can burst, producing peritonitis, and open, which, among other signs, is evidenced by bleeding with pus, dehydration, frequent urination and lethargy.

If the abortion occurs in half of gestation, it is likely that the mother and the rest of the pups are in danger. In this phase the abortions can be spontaneous, product of a trauma, a serious uterine infection or other reasons.

In both cases it will be essential to go to the veterinarian to perform the necessary tests that guarantee the health status of the parent and the puppies that are yet to arrive. Most likely, the specialist will request a ultrasound or an x-ray to assess the state of pregnancy.

Hello, how am I with my cat that I do not know if she is pregnant and it is difficult for me to take her to the vet, but she walks a lot inside the house on top of one, and today I discovered that she is losing blood and I am super bad because I do not know that she can be happening. I have a cute 2 month old kitten that he wants to play when he is a little boy and she gets bad at all and it wasn't like that before. - Janet Colonel

Red blood

If it is red it can indicate that one of the fetuses has died and that the body is going to reabsorb it. In this case the cat will continue to make a completely normal life, although it does not hurt to take her to the veterinarian to examine her because she might need antibiotics.

Black blood or green liquid

If it is black or expels green liquid it is because or has a bacterial infection or because there are one or more kittens that are dead and rot, instead of reabsorbing.

When this happens, the cat will have loss of appetite, apathy, fever and vomiting. To recover as soon as possible, you have to take her to the vet as her own life is at stake.

Veterinary care is key

There are no home remedies that can treat the problem. In addition, we must not give him medicines for humans because, if we do, we could poison the cat and end his life. That blood, especially if it is black, is something that must be taken very seriously.

In the veterinary clinic or hospital they will examine it, they can tell us exactly what it has and how we should act so that everything goes well.

We hope you found this article useful. 🙂
