Injections for cats instead of sterilization

What happens to a cat during heat?

Estrus is a process caused by the activity of the gonads, which causes sexual arousal in the female. The first heat occurs when the cat reaches puberty, when her body is completely ready to bear offspring, i.e. at approximately 7–8 months of age.

Beloved pets change dramatically, constantly scream shrilly, become overly affectionate, intrusive, or, conversely, show causeless aggression. Animals often lie on the floor and squirm, arch their backs, and rub against all objects in the house. Sometimes during this period they relieve themselves not in the tray, but anywhere in the apartment. In cats, this condition usually lasts about 2-3 weeks.

How to prevent a cat from "walking"?

Cat owners most often use special veterinary drugs to suppress the sexual desire of their pets. The mechanism of their action of drugs usually does not cause the cessation of estrus, but reduces the manifestation of unpleasant symptoms. After receiving a dose of such a drug, the animal becomes calmer and stops screaming.

There are also medications on sale that contain hormonal substances. This group of drugs can really affect the physiological processes in the pet’s body and stop or prevent estrus. Hormones in some cases negatively affect the health of cats, therefore, when choosing a medicine, you need to take into account the condition of the animal and the degree of concentration of the active substances in the product.

Sterilization: age, methods, consequences

Sterilization is the most effective method of preventing sexual desire and the birth of unwanted offspring. The operation is performed under anesthesia. The surgeon removes the animal's ovaries, so sex hormones are no longer produced. As a result, estrus no longer occurs.

It is recommended to spay or neuter females in adolescence after puberty, but before the cat's first heat, which can begin at 7-9 months, so it is best to do the operation at 5 or 6 months. Young nulliparous cats generally do not experience postoperative complications. Veterinarians sterilize cats up to 10 years of age, since after this age the animal may not survive the operation, and in addition, anesthesia can cause complications.

Some people mistakenly believe that sterilization has a bad effect on the health of cats and changes their character and behavior for the worse. Experts say that surgery to remove the gonads and uterus relieves pets from hormonal fluctuations, prevents unwanted pregnancies, as well as the occurrence of cancer.

Surgical sterilization or injections from walking

When choosing the type of sterilization, you should weigh all the advantages and disadvantages of the method.


Veterinarians believe that the most optimal age for sterilizing cats is 6 months.

In addition, the general condition of the pet and its age are taken into account.

Hormonal injections for cats against pregnancy

Of course, the most radical, most effective and healthiest thing is castration-sterilization. The reproductive instinct is something that a cat cannot cope with on its own.

It is during these few periods of the year that she completely stops thinking, and all her desire and behavior is aimed at prolonging the race.


A cat comes into heat for the first time between 7 and 9 months of age.

The estrus period takes place in several stages, which can be determined by the following signs:

  • Swelling of the reproductive organs;
  • Frequent trips to the litter tray;
  • Frequent licking of the pelvic area;
  • Loss of appetite;
  • Increased need for affection - the pet begins to intensively demand attention and rub against surrounding objects, falls on its back and rolls around, making purring sounds;
  • Attempts to escape from home;
  • The cat constantly meows, does it loudly and protractedly;
  • The animal arches its back. Raises its tail and steps with its hind legs.

The cat wants to go for a walk. The pet owner does not enjoy this behavior either.


Cats reach final sexual maturity between 1 and 1.5 years.

Removing symptoms, as well as completely eliminating the urge to estrus, asking a cat that does not lead to pregnancy, is possible using 3 methods:

  1. The use of drops that reduce libido;
  2. Sterilization is a surgical procedure that involves partial or complete removal of the reproductive organs;
  3. Injections that reduce the reproductive instinct.


Immediately after administration of the drug, a slight local painful reaction is possible.

Contraceptive injections and pills, with a certain dosage, affect the cat’s hormonal levels in a short period of time, resulting in a delay in estrus.

Pros and cons of contraceptive injections

This means of chemical sterilization has both positive and negative sides.

It is worth resorting to the injection method after weighing the pros and cons.


The administration of the drug stops the development of estrus in a cat and removes all its negative manifestations

pros

  • Does not cause complications after surgery, there is no rehabilitation period. Sterilization does not require preoperative preparation and eliminates infection and contamination of blood and sutures, including suppuration, scars and cicatrices.
  • The process is simple and can be carried out at home in the presence of a veterinarian or following the instructions received from him.
  • No risk to the animal's health during anesthesia. Most cat breeds, as well as young and older individuals, do not tolerate anesthesia well. As a result, allergic reactions and dysfunction of the cardiovascular, respiratory and nervous systems develop.
  • Self-healing of the reproductive properties of the body. Hormonal injections are a temporary measure; after a certain time, the ability to become pregnant, bear and give birth to kittens is fully restored and does not cause complications.
  • The minimum number of contraindications in comparison with surgical sterilization.
  • Complete elimination of injury, pain and rehabilitation of cats.
  • Possibility of use in the role of correction of cat behavior, in order to avoid walking.
  • The speed of action of the drug on the pet’s body.

Conditions and instructions for use of injections

Injections are given under the following conditions:

  • Age over 10 months;
  • No allergic reaction to the drug;
  • The pet is in normal health.

Mode of application:

  • The first injection in the withers is given during the period between estrus;
  • A second injection is given after 3 months;
  • The third injection is given 7 months after the start of the procedure;
  • Control injections are administered every 5 months.

The drug is administered to the cat only during periods of sexual calm and in a veterinary clinic.

Hormonal injection for a cat from estrus - danger and harm

What are the risks of sterilizing cats with an injection?

The owners of any cat sooner or later face the question of what to do with its sexual instinct. During estrus, cats become insane, and after an uncovered estrus they walk around in a bad mood and show aggression towards their owners. All this cannot be liked, and therefore many decide to somehow fight sexual desire. In this article we will talk about what a hormonal injection is for a cat in heat and whether injections are good for cats instead of sterilization.

Contraceptive injections for cats are injections that sharply disrupt the animal’s hormonal levels, as a result of which estrus is postponed for some time. These injections are popularly called “antisex cat injection”, “counter sex”, “cat injection from a cat” and similar common words. In fact, we mean such drugs as “Covinan” (the active ingredient is prolygestone, a synthetic analogue of the hormone progesterone), “Depo-Provera” (the active ingredient is medroxyprogesterone), “Depogestone”, as well as a number of other medications.

Out of ignorance, people think that one injection will solve the problem forever, and then they are surprised to find out that the cat is walking after the injection. You need to understand: to permanently suppress sexual function, injections must be done regularly. For example, the Covinan injection is given according to the following scheme: 1st injection - during the period of sexual rest between estrus, 2nd injection - 3 months after the first injection, 3rd injection - 4 months after the second injection, subsequent injections are given once every 5 months. That is, if a cat has gone on a spree, she cannot be given an injection until her heat is over. Moreover, the injections must be prescribed, given and their consequences monitored by a veterinarian.

Properties, principle of operation

Depo-Provera is a synthetic hormonal preparation of progesterone.


Depo-Provera for cats

The drug suppresses ovulation, which makes conception impossible, since the egg does not leave the follicle. If the animal has already started estrus, then there is no point in using the drug.

The sex hormones included in the medicine quickly saturate the body, preventing complete maturation of the egg and ovulation. Synthetic compounds act more pronouncedly and intensely, which is why synthetic progesterone is used in Depo-Provera.

The drug has a large number of side effects, since disruption of natural hormonal levels affects the entire body.

Important! If there are no contraindications, a cat that is not allowed to be bred should be sterilized if possible. Thus, the owners will forever relieve themselves of the problems associated with estrus.

STERILIZATION OF CATS BY INJECTION - PRICE

Injections for a cat to prevent it from wandering, that is, against pregnancy and estrus, cost about $30 per drug. One bottle for this price is enough for several times. Getting an injection from a veterinarian is inexpensive, and it doesn’t even need to be considered if you are able to purchase the drug itself.

Interestingly, buying an injection medication for several uses and injecting a cat against cats costs about the same as performing a sterilization operation. Only injections do not solve the problem forever, but sterilization does, and even does not have the terrible health consequences, which you can read about below.

What to replace it with?

Chemical castration of cats can cause a serious blow to the health of your pet. Therefore, some owners solve the problem with special tablets or drops. However, like injections, these drugs also have a lot of contraindications and restrictions, but still there are fewer of them. The main components included in the drugs change hormonal levels and sometimes lead to complications in the form of tumor formation.

The only relatively safe method is sterilization surgery. To prevent the cat from wandering, castration is performed, and the cat's ovaries are completely removed to prevent pregnancy. After surgery, recovery and rehabilitation are required. Special care for a sterilized animal is also necessary. However, after such a procedure there are no such terrible complications, the animal leads its usual lifestyle, but there are no longer hormonal surges and sprees.

CAT AFTER HORMONE INJECTIONS

Injecting a cat for heat is a quick and simple solution that would be ideal if it did not have dire consequences. Drug manufacturers indicate them in their instructions. Yes, they do not occur in all cats. Some people spend their entire lives on injections and nothing. But many face the consequences one way or another. Let's list them:

  • increased appetite and weight;
  • apathy;
  • enlargement of the mammary glands;
  • pyometra (purulent inflammation of the uterus);
  • breast tumors;
  • diseases of the endocrine system (diabetes mellitus);
  • ovarian and uterine cysts;
  • cancer. photo

After the cat has been given a “walking shot so that she doesn’t get pregnant,” various kinds of disorders begin in the body, because... sex hormones regulate not only reproductive function. At the same time, the hormonal background accumulates, although it is suppressed, and sometimes leads to irreversible consequences. After all, the need for reproduction does not go away; injections only drown it out. And suppressed hormones over time lead to a real explosion in the body. This can happen years after the first injection, or maybe as early as 2 months.

Side effects of the drug

For those cat owners who want to find a “magic” remedy to prevent heat, it is important to know that such drugs may not be completely safe. In addition to the fact that you need to follow special rules when performing injections, you should carry out treatment only after consultation with a specialist. He will warn you how Covinan can be dangerous for cats. Side effects do not occur so often, but they are quite unpleasant for both the animal and its owner:

  • Many cats have an increased appetite and begin to gain weight;
  • some owners note lethargy and lethargy of the animal after treatment;
  • the mammary glands may enlarge and even develop a tumor;
  • sometimes purulent inflammation of the uterus occurs;
  • the activity of the endocrine system may be disrupted;
  • local reactions include hair loss or lightening at the injection site.

WHAT IS BETTER - STERILIZATION OF A CAT OR INJECTIONS

If you want the best for your pet, but don’t want her to ask for a cat and give birth to kittens, then the only correct solution to the problem is sterilization. This is recommended by all veterinarians without exception, as well as by the MURKOTIKI website, which has collected numerous reviews from owners about sterilization and what injections are that sterilize a cat.

Perhaps now it seems to you that sterilization is an unnatural solution, but in fact, only it allows the cat to stop pestering its owners, to suffer and languish from an unsatisfied sexual instinct, but to remain healthy and sexually neutral. Read more about sterilization to make your final decision.

For now, let's say that castrated cats are generally healthier than even females who give birth regularly. The fact is that childbirth wears out the body. And a sterilized animal is a happy animal with life, whose only thing on its mind is to eat, play, cuddle and sleep. Isn't this the ideal cat's life?

Many people are frightened by the prospect of abdominal surgery, so they decide to undergo injections. But injections are much more dangerous. As we said above, such cats with a high degree of probability will sooner or later end up on the operating table, but with pathologies that are difficult to operate on. Healing after such an operation is also a long process. And there are often inoperable conditions when it is better to euthanize the cat. Therefore, you must clearly remember that in many cases, constant hormonal injections = surgery or early death. In the case of planned sterilization, rehabilitation will take 4-5 days, and after 10 days the cat will already be running around as if nothing had happened.
