Castration of cats – What you should know. Since cats, like all other animals, have the natural urge to reproduce to preserve the species, they start mating from a young age of five to six months. Why you should have your cat neutered or sterilized, we want to explain in detail in this article.

1. The purpose of castration

Castration brings some advantages for the animal. We have compiled an overview here:

  • Higher life expectancy compared to uncastrated cats
  • They are less aggressive
  • Reduced risk of accidents for free-riders, as the area is significantly reduced (no more “strays”)
  • Hangovers stop marking in the apartment
  • Cats no longer show symptoms of rolling
  • The animal becomes more trusting and wants more closeness
  • Not an unwanted offspring to look for at home

2. Castrate or sterilize?

It is often assumed that castration is carried out only in males and sterilization only in female cats. But that is not the case! Both sterilization and castration can be used in cats AND cats. But what is the difference?

Both methods have the purpose of making the cat or the cat infertile. They differ only in the medical procedure and in its effect.


Castration prevents hormone production for life by removing the hormone-producing glands. Cats are therefore surgically removed from the ovaries and males. The setting of hormones brings with it the above-mentioned advantages.


Sterilization is also causes the cat or cat to be rendered infertile. In the case of cats, however, only the semen ladders and in cats the opiopian tubes are severed. Therefore, the animals remain hormonally active after this procedure, as the hormone production is not stopped and the reproductive instinct remains. The above-mentioned advantages do not apply after sterilization.

3. At what age can a cat be neutered?

As a rule, cats reach sexual maturity between 6 and 10 months. At the latest, when cats start to mark or cats become rolled, the keeper knows that sexual maturity has been reached. Due to various factors, cats can reach sexual maturity after only 4 to 5 months.

Castration before sexual maturity – yes or no?

Early castration is particularly advocated for free-riders, as this can prevent unwanted offspring. Although small kittens are very cute, it is not always possible to find a home for the little ones. Early castration can also prevent diseases such as mammalian tussers.

On the other hand, it is stated that the kitten could not yet be fully developed and only partially grows after the procedure, so that it would be possible that the cat remains smaller than its counterparts.

At the end of the day, the timing of castration is a very individual decision. Is the animal a freeman or an apartment cat? Depending on the conditions of keeping, the date for the procedure should be arranged with a veterinarian, as the latter is best placed to assess the stage of development of the cat on the basis of his examinations.

4. What should be considered in case of castration

Castration is a routine intervention that is almost harmless. Depending on the sex of the animal, the procedure during the operationalso varies. On the positive side, the four-legged friend can be taken home on the same day.

The cat or cat is narcoticized during the entire procedure to prevent the animal from feeling pain. After completion of the operation, the cat is prescribed painkillers. Since the procedure is more serious for female spatients than for males, because the abdominal wall has to be cut open, they will have to take the painkillers for 3 days, while a hangover will only get the painkillers for one day.
