As sexual maturity approaches, by 6 months of age, you should sterilize your cat, both males and females.

  • The animal will not have the need to escape to the street and will save all the dangers that this entails, such as fights, parasites and infections (Mortal viruses such as Feline Immunodeficiency and Feline Leukemia).
  • It avoids in the females the psychological pregnancy, the piómetra and some mammary tumors, and in the males, testicular tumors, perianales hernias, tumors of perianales glands. In general, the longevity of the animal increases.
  • The discomforts of their sexual behavior are eliminated, in the case of females: constant and acute meowing, lack of appetite, and change of attitude in general and sometimes marking in the house with urine. The males get nervous, try to escape, if they have access to the outdoors, most die before two years, run over or for some other cause, since they can travel several kilometers looking for a female. They also become irritable, and mark the house with the unpleasant smell of their urine).
  • Castrated cats turn out to be more docile, affectionate and calm animals, improves their mood and character, makes them more fun and takes away their anxiety, something very noticeable in the case of males, (they do not lose their instinct to hunting, neither its agility, nor its elegance).
  • It is absolutely false that a neutered animal becomes fat. It is up to us to exercise enough. Sometimes they have a greater appetite, especially the first months after surgery. If necessary, we can replace the feed with a “light” version, in this way and if the cat continues to exercise, it will NOT gain weight.
  • And finally our pet does not escape to the street to satisfy his sexual instinct and therefore, he will not get pregnant or become pregnant and will not be responsible for bringing future stray cats into the world. A cat can have three to four litters a year, with an average of four puppies per litter. Many of these kittens end up living in the streets in bad conditions, digging in garbage cans or sewers.

Sterilization of cats and kittens FREQUENTLY ASKED QUESTIONS

You have included someone hairy in your family. Fantastic! When your kitten is still too pretty and small, it's hard to imagine her with her own kittens.

However, when your cat reaches sexual maturity between four or six months of age, she may have kittens still being a kitten herself! Therefore, as responsible for your pet, you should start considering sterilizing your cat from the beginning.

Sterilizing felines means that your cat will avoid unplanned pregnancies and be protected from some diseases.

Castrating or spaying your cat does not have to be a difficult decision. Our pet care team is at your disposal to tell you everything you need to know about sterilization, so you can make the best decision for you and your cat.

Sterilization is a common and usual operation that involves the removal of the sexual reproduction organs of your cat. It is also known as "sterilization" for females and "castration" for males.

For females, sterilization involves removing the ovaries and the uterus, although sometimes only the ovaries are removed. This is usually done by a small excision on its left side, and can also be done below, longitudinally.

For males, the procedure involves the removal of their testicles. The procedure is simpler in males and does not require any stitches.

The sterilization operation is very simple and your cat will be anesthetized to ensure he feels no pain during the procedure.

After the operation, the veterinarian will treat your cat with analgesic injections to help with the postoperative discomfort. You should also be provided with anti-inflammatory and analgesic medications to give them to your cat at home.

Since the procedure is much less invasive in males, they will only require medication for one day. Females will require medication for about three days to help them recover as soon and easily as possible.

Sterilizing a cat has multiple benefits for your pet. For example, your cat will be less likely to get some diseases, and avoid unwanted pregnancies. Among other advantages of sterilizing your cat, the following stand out:

  • Stop the mischievous behavior that comes with sexual maturity, such as the spraying of urine to mark their territory.
  • Sterilized cats are less likely to move away from home, which protects them from being involved in traffic accidents and fighting with other cats.
  • Your pet can become more affectionate. Cats often become friendlier.
  • A reduced risk of contracting some diseases, such as feline leukemia or feline AIDS.
  • Less likely for your cat to develop a uterine (uterine) infection.
  • If cats are sterilized at an early age, they are less likely to develop breast (breast) cancer.

We recommend sterilizing your kitten before it reaches sexual maturity and is able to have its own kittens. This usually occurs between four and six months of age. You will be able to recognize when your cat reaches puberty, as cats will meow with intensity, and males are likely to spray urine to mark their territory

Some shelters and veterinarians recommend cat sterilization at an early age, from 12 weeks or even earlier.

To protect your cat from having or causing unwanted pregnancies, keep it at home until it has been sterilized.

Myth: You may have heard that it is good for cats to have a litter of kittens before being sterilized, but our Pet Service team confirms that, in reality, this is not true.

To sterilize your cat, you will have to make an appointment with your veterinarian. I may ask you to take your cat for a pre-anesthetic study before the operation.

Your veterinarian will ask you not to feed your cat the night before anesthesia, keep the water available normally, but remove it the morning of its operation to prevent it from drinking before the intervention.

Normally, you will have to leave your cat with the vet in the morning and pick it up later.

If you want to sterilize your cat and can't afford that expense, talk to local animal protectors. Some animal protectors direct financing plans for sterilization, something that can help you cover the cost of sterilizing a cat.

All cats tend to be a little sleepy after their operation, but they will regain their normal vitality very soon. Apart from this, the recovery process varies by gender, since the operations are different. There are a few things you can do to help your hairy child heal after being sterilized.

  • Sterilization should have little or no side effects in males.
  • Stay or stay close to him on his first night after the operation, just in case.
  • Your veterinarian should give you anti-inflammatory and analgesic medication for your cat, although he will only need it one day.
  • You can go outside again normally the next day.
  • As the castration operation is more invasive, females need more time to recover.
  • Stay or stay close to her on her first night after the operation, just in case.
  • Your veterinarian will provide anti-inflammatory and analgesic medication for your cat: he will need to take it for about three days after the operation.
  • Your cat will need to wear an "cone" or Elizabethan collar, to avoid licking or biting the stitches.
  • The veterinarian will schedule revisions three and ten days after the operation of your pet. Keep your cat at home until the vet gives you approval after ten days, by then, you can play outside normally.
  • If non-absorbable stitches are applied, the veterinarian will give you an appointment to have them removed again, usually 7-10 days after the operation.

Weight gain

Sometimes, sterilization is related to weight gain. Although the operation is not entirely responsible for the weight gain of cats, it can prevent them from wandering in search of a partner. This means that they move less, and they may gain a couple of kilos.

If you notice that your pet is gaining weight, you can have him exercise by playing with him or by walking with a harness. Use our game tips guide to inspire you and create your own game show. GAME TIPS ARTICLE

Urinary tract problems

After sterilization, your pet will be more likely to develop urinary tract problems. If you detect any change in your cat's urinary habits, such as urinating more often, squatting without urinating or urinating blood, talk to your veterinarian.

  • Your cat will be in heat approximately every three weeks once she has reached sexual maturity. During the heat, you may meow hard and be very restless, something that can make family life in your home difficult.
  • When your cat is in heat, you will have to be very careful to protect her from the males in love with the area and prevent her from becoming pregnant.
  • Your cat could have up to three litters a year, with a maximum of six kittens in each litter. This can be very expensive.
  • Your cat may be more predisposed to wander away from home, increasing the risk of a traffic accident.
  • Unsterilized males tend to be more aggressive and are more likely to fight with other cats. They run the risk of suffering injuries and spreading diseases.
  • Unsterilized females are at greater risk of developing breast tumors (breast cancer) around 6-7 years of age. Check regularly if there is any lump in your cat's breast area and, if you find something that worries you, talk to your veterinarian.

As a general rule, cats do not show obvious physical symptoms until they reach the second or third week of pregnancy.

If you think your cat may be pregnant, contact your veterinarian to get out of doubt as soon as possible. Read our tips on how to detect the signs of pregnancy to know what symptoms to consider.

It is possible that your cat may be sterilized even while pregnant, which will interrupt her pregnancy and prevent her from becoming pregnant again in the future.

Your veterinarian should provide you with more information about sterilizing a cat while pregnant, to help you make a decision.

The sterilization of kittens and cats depends on your personal circumstances. Before making a decision, please consider what is best for you and your cat.

Feline sterilization

It is common for insecurity to invade animal lovers when it comes to spaying or neutering their own cats. Sterilization at an early age seems to be essential when seeing so many cats without owners and protectors of overflowing animals. But is it going to affect my cat if I deny him the chance to have young? What is the most appropriate time for sterilization? What are the differences between spaying and neutering? And when is it better for the intervention to take place?

Regardless of whether your cat comes from a protector or a breeder, at some point the question of sterilizing it will arise. Protective cats are usually already sterilized before being delivered to new owners and, as long as you are not interested in founding a hatchery, it is also advisable to sterilize breed cats.

Why sterilize?

Although humans tend to be more sentimental even when it comes to sterilizing our cat, we must keep in mind that they get carried away by their instincts when it comes to breeding. If cats acted totally guided by their instincts, they would have several pups each year. In this way, a pair of cats can procreate up to 80 million descendants in 10 years. It is very unlikely that such a large number of kittens will be lucky enough to find a suitable home with loving owners and proper food. For this reason, it is essential to sterilize cats in time and thus avoid having unwanted offspring.

Moreover, often non-sterilized animals are exposed to unimaginable stress. While the non-castrated males begin to mark the territory with the arrival of puberty, those who are are stop traveling kilometers and kilometers a day in search of potential sexual partners. In addition, they are more likely to suffer accidents and infectious diseases, as well as to fight with other animals of their species. Females in heat have suspicious behavior and are always on the alert to find potential males. They roll on the ground, raise their backs in the air, meow to call the males and, often, they even forget to eat. If they fail to mate, hormonal changes in your body can lead to diseases such as cysts, breast tumors or inflammation of the uterus.

On the contrary, neutered animals stop performing many behaviors guided by instincts. Their lifestyle is quieter and often healthier, so they can reach a much more advanced age than their non-castrated partners. This also excludes the possibility that their offspring end up in an animal shelter or contribute to feline misery.

Simply put, sterilization is beneficial for both the cat in particular and in the broader context of animal protection.

How is castration performed?

Twenty years ago female cats were sterilized while males castrated. This process was replaced by the simple procedure of neutering both sexes. Meanwhile, more and more experts recommend castration at an early age, before puberty begins. If the operation is carried out before the sixth month of life, not only unwanted offspring are avoided, but it is also much simpler and safer than in older animals.

In the case of males, castration is a small surgical procedure that only lasts about twenty minutes. This consists of ligating the spermatic cord and cutting it approximately half a centimeter further. Often no single point is required.

Castration of females is performed in a manner similar to that of males, the ovaries are cut, ligated and extracted. This procedure leaves a small incision in the stomach, which closes with few stitches. This intervention lasts about an hour.

Animals can return to their homes a few hours after the operation. It is important that the first hours after surgery the cats are in a quiet environment so that they recover slowly and orient themselves.

What happens after castration?

What happens next? Do sterilized cats change? If you believe everything you read on the internet, sterilized cats get fat and become more lazy and indifferent. This is not entirely true, although sterilization does interfere with the hormonal balance of the cat and, therefore, affects his physical and mental state.

The heat disappears, males who previously performed marking with urine can give up this habit after castration. However, this is not guaranteed, especially if the operation has been performed once the cat is well advanced at puberty.

Sterilized cats become calmer and more relaxed due to lack of hormonal fluctuations. In fact, they move less and your body needs less energy for reproduction, but at the same time, your appetite may increase. The feeding of sterilized cats should be adapted to prevent overweight.

Those who are against castration often claim that neutered cats are not going to develop healthily because it could adversely affect the increase in head size and because the reduction in urethral size could cause sediments or urinary stones. However, this is not demonstrated by the studies. The Feline WINN Foundation, in collaboration with the American Association of Veterinary Medicine, discovered that sterilization at an early age does not affect the diameter of the urethra or body growth. A large head has its cause in genetics, and is not a consequence of sterilization. While spayed cats are less aggressive, castration itself does not change the fundamental character of the cat.Your cat will have more calm and time to play with you, frolic and snuggle, although it will continue to maintain its initial independence.

So don't worry! Sterilization only positively affects your cat.

Sterilize your cat: a good decision?

Many people doubt about the benefits of sterilizing their pet. They consider that, in doing so, they deprive the animal of reproduction.

While this is true, more important is to consider that this decision prevents procreation without control, unwanted offspring and subsequent abandonment.

Cats are very fertile animals that have several jealousy a year and in each litter they can give up to 7 kittens. Many of whom, unfortunately, end up surviving on the street.

When sterilizing your cat you choose a responsible attitude versus the ability to choose.

In females:

  • Removal of the sex glands: The ovaries and uterus are removed. In this case a surgical intervention is performed with general anesthesia.
  • If removal is not desired, a tubal ligation may be chosen when cutting oviconducts.
  • In the case of males:

    • Excision of the testicles by surgical intervention.
    • Failing that, a vasectomy in which the spherical pathways are cut.
  • There are differences with respect to these methods, both in females and males. In males, both reproductive capacity and heat are removed, because the sexual organs are removed. While in the second option (tubal ligation and vasectomy) the organs are maintained and only the ability to reproduce is removed.

    If what is sought is to avoid the behaviors associated with the mating season, the ideal is to go for the removal of the organs. These behaviors are cases such as marking the territory, meows or fights, among others.

    Advantages of sterilizing your cat

    • Unwanted pregnancies are avoided.
    • The cat population is controlled and abandonment is avoided and all that entails.
    • In the case of the neutered male, the practice of marking the territory with urine during the reproductive period is significantly reduced.
    • For the castrated female, jealous behaviors such as meowing disappear.
    • In both behavior stabilizes. They become calmer as anxiety and nervousness disappear linked to the search for mating and hormonal changes.
    • Health problems linked to sexual organs are reduced. In the case of cats, those risks associated with childbirth and problems in the reproductive system, as well as tumors of the uterus or breasts. In males, the risk of suffering diseases in the prostate or testicles decreases.

    When to perform sterilization?

    On this point there are various opinions, and therefore it is better to consult the veterinarian.

    The more traditional positions consider that The ideal age for sterilization is after the first heat, around 6-8 months.

    But nevertheless, many currently advise sterilizing the cat before that stage, that is, at 4 or 5 months. Thus avoiding the danger of a surprise pregnancy and the behaviors associated with heat.

    However, it is possible to perform the procedure(both the surgical and the non-surgical option),at any age of the animal. Even if he is an adult and has already had a baby.

    Take care of being overweight

    An extended fear regarding the consequences of sterilization is the risk of obesity. In this sense, although the cat modifies its nutritional needs, care simply goes through controlling its feeding. Buying special food for sterilized animals and giving a balanced meal with proper monitoring is enough to avoid being overweight.

    Definitely, sterilize your catit is beneficial. For the pet, health risks are reduced. For the family, unexpected pregnancy and annoying behavior are avoided. And in the case of neighbors and community, by controlling the proliferation of animals in the street.

    Feline sterilization: better safe than sorry

    Sterilization in male cats is well indicated when it is clear that you do not want to raise the animal. The advantages are obvious and very conciliatory for our coexistence With cats and also we can prevent possible problems related to our pet's reproductive system.

    When a cat reaches adulthood and begins to feel the sexual desire to attract females, it begins to develop a series of very undesirable patterns for its owners such as house leaks in search of females, marking with urine throughout its territory that includes beds and sofas, constant meowing late at night ... This is the effect of testosterone on your body that drives you to report your predisposition as a male available to other cats in the neighborhood, which can become a real ordeal.

    That is why it is recommended to practice sterilization, since we will avoid these behaviors and eliminate the stress that is supposed to be available sexually but not having the possibility of consummating your sexual appetite. Ideally, the operation should be performed between 6-7 months, as is the case with Rotko, when he has not yet fully matured and has not developed adult male behaviors. In this way you will not have taken habits that you can continue repeating in spite of having been sterilized. On the other hand, with sterilization we will be avoiding all pathologies related to the testicles, including tumors.

    With this surgery, despite what some people think, the cat does not change character or become lazy. But if there is a risk to gain weight if you continue to eat the same amount as before because with sterilization the sexual function in your body disappears, which implies a lower need for caloric intake for your body. For this, the remedy is simple. Simply reduce the amount of food or switch to a specific feed for sterilized cats.


    The sterilization of a cat is a simple and routine surgery but it implies integral anesthesia, so there is no greater risk than what it implies. To ensure that the operation will be successful, a preoperative procedure is always performed. It consists of a blood test and an x-ray to ensure that all the parameters of your body are normal.

    After weighing Rotko and supplying the medication and sedation, anesthesia is administered, the area is shaved and he is relocated to the operating table to begin the operation. With a small incision in the scrotum area, we externalize the testicles, suture the vessels and remove them. Once this is done with both testicles, we put internal points and disinfect the area. It's that simple.

    Rotko remained A few hours in hospitalization while recovering from anesthesia and the same day he could go home. The postoperative treatment that he had to carry out after this intervention lasts one week and consists of cures with chlorexidine and the administration of antibiotic and anti-inflammatory. After this week, Rotko is the same as ever, as soft and affectionate as the first day.
