Cats generally will not go into heat again after being neutered. Because the sterilization operation of female cats removes the cat's uterus and ovaries at the same time, while the castration operation of male cats directly removes the cat's testicles. For both female cats and male cats, these organs are normally secreted by cats. The main site of sex hormones, so as long as the operation is successful, generally speaking, there is no possibility of cats going into heat again. However, even though the cat has undergone sterilization or castration surgery, the level of sex hormones in the cat’s body has not completely dropped in the short term. This part of the sex hormones needs half a month to a month to be metabolized. After the metabolism is complete, the cat will generally not go into estrus again. of.

If a cat is still in heat after being sterilized or castrated for a period of time, there are three reasons:

1. The sterilization surgery of the female cat did not completely remove the ovaries or uterus, and the removal was not clean. The growth capacity of the uterus and ovaries is very strong. If the uterus or ovaries are simply ligated, the remaining parts will grow rapidly relying on side blood vessels. In this case, the cat may go into heat again.

2. The male cat has cryptorchidism and the cryptorchidism has not been removed. Cryptorchidism in male cats is actually very easy to find. When you find that a male cat has only one testicle, you can usually confirm that the cat has cryptorchidism. The other testicle may be under its skin or in its abdominal cavity. This Only a B-ultrasound can be done to confirm. As long as a second operation is performed to remove the cryptorchidism, the cat will not go into heat again.

3. Caused by glandular abnormalities. All hormones in animals are secreted by different glands. If the glands are abnormal, they will secrete sex hormones and show signs of estrus again. This requires professional examination to confirm the diagnosis.
