Magic Injection- Covinan and Depot-provera

– Is it possible to give a cat such a prick, well, so that she doesn't ask for a cat? - from the application to the veterinary clinic

The question is simple, nevertheless, it has a global scale, is relevant for all times, all countries and peoples – where there are cats, there he exists.

And in order to answer it, we need to sort something out, and sort it thoroughly.

Believe me, it's worth it.

Only there is no prince, where did he go?..

Oh, these cat's "wishlist"! More precisely, their lack of demand.

Starting from 8-10 months (or even less!) at that age, the light bulb of the instinct "multiply and multiply!" begins to blink and send a signal in the cat's head, the one that suppresses all other instincts and turns the cute creature into a small monster - screaming, rolling on the floor, leaving odorous marks. The instinct that makes the owner's life look like living on a volcano - it is not known when it will "explode", which of the nights will be sleepless.  

To satisfy the sexual instinct, at least a sexual partner is required. Oops, and no one was going to provide it to the cat. As well as creating conditions for the "dating process". And the result of the meeting – kittens – is not needed by anyone… Let's not talk about how detrimental this affects the cat itself – this is described in detail HERE. Let's talk about solving the problem.

What to do?

Of course, the most cardinal, the most effective and the healthiest thing in the whole wide world is CASTRATION-STERILIZATION. But the operation requires some trouble from the owner, material and time costs and, finally, the desire to do it. It happens that something from this list is missing.

Then chemical melee weapons are used - Ex, Stop-intimacy, Sex barrier, Counter-Sex and other "contrasts" - pills or drops that interrupt estrus. Alas, they are all short-term or "it used to help, but now it doesn't take." Clearly something more effective is required.

And that's when the owner comes to the idea that the pet needs a magic prick, about which a neighbor (friend, acquaintance or work colleague) told: "you bet, and that's it!"

Hormonal contraceptives of prolonged action

There are several of them. But the two most popular are Covinan and Depo-provera. We will consider them.

Covinan (Covinan) is a veterinary hormonal agent designed to inhibit sexual hunting in bitches and cats. The active substance is proligeston, a synthetic analogue of progesterone.

Proligeston is a steroid hormone that prevents the development of estrus. It increases the viscosity of mucus in the uterus, which prevents the introduction of a fertilized egg, inhibits cell hyperplasia and breast secretion. When introduced into the phase of sexual rest (anestrus), proligestone maintains a low concentration of LH - luteinizing hormone in the cat's body, which provides contraception of the animal. When the drug is canceled, the amount of proligestone in the body decreases, the normal level of LH is restored, and the contraceptive effect ceases.

How to do it correctly

To develop a stable sexual rest in a cat , Covinan is used according to the following basic scheme:

INJECTIONS TIME INTERVAL
first injection during sexual rest (anestrus)
second injection 3 months after the first injection
third injection 4 months after the second injection
subsequent injections 1 time every 5 months

That's how its manufacturer, Intervet International B.V., the Netherlands, offers to put Kovinan. Her specialists conducted scientific research, taking into account the entire complex process of hormone production by the pituitary gland, hypothalamus and ovaries of a cat – all in order to make the drug the most effective and least safe. And this is important, because hormonal drugs are not jokes. They also have a reverse side.

Side effects (from the instructions): When using the drug in rare cases, pyometritis, endometrial hyperplasia, a slight increase in body weight, increased appetite, apathy, slight hypertrophy of the mammary glands are possible. Immediately after administration of the drug, a minor local painful reaction is possible. At the injection site, it is possible to lighten the coat and slight hair loss.

The most frequent negative consequences are:

pyometra (purulent inflammation of the uterus)
breast tumors
diseases of the endocrine system (diabetes mellitus)

Now let's look at the contraindications (from the instructions): Covinan is not used in pregnant or lactating animals; during estrus (estrus); animals with diseases of the genitourinary system; animals with prolonged vaginal discharge. Animals suffering from diabetes, the drug is used with careful monitoring of blood glucose levels.

It seems that everything is simple – injections are put on a simple schedule during the absence of sexual hunting. And what do we have in reality?

And here's how it's usually done

As we have always had, the system works "until the thunder breaks ...". While the cat is calm, its owner is also careless. Here she screamed a good obscenity, rolled on the floor, began, God forbid, to shit in the wrong places — that's when the owner runs with her to the nearest hospital. He comes running and says, "Do something!"

And veterinarians are different – good and not so good. A good doctor from the possibilities of "something" really wants to do an operation – "the healthiest in the whole wide world."

It is sterilization that the doctor offers in the first place. But the owner believes that the injection is the best solution to the problem.
Then a good doctor tells about the possible consequences of such a hormonal injection. But the owner still believes that the injection is the best solution to the problem.
Then a good doctor examines the cat and, finding signs of estrus, explains that it is a contraindication to the administration of the drug and tells about the correct scheme. But the owner still insists on the injection.
Then a good doctor puts this injection. Why? Yes, because in case of refusal, the stubborn owner will go to another clinic, where there may not be a very good doctor.

Not a very good doctor will give an injection right away.

Depo-Provera (Depo-Provera) Unlike veterinary Covinan, Depo-provera is a medical drug, one of the first synthetic progesterone hormones developed to prevent conception in women (as well as as a means for the treatment of certain gynecological and oncological diseases). The active substance is medroxyprogesterone. It happens in the form of a suspension or tablets.

Due to its ability to suppress ovulation, Depo-provera is used as a long-acting contraceptive.

The drug has limitations on use and a wide range of side effects, including reactions from various organs (in women). For cats, a contraindication is also estrus. The same negative consequences are also possible.

Depot-provera is preferred by veterinarians at clubs and kennels, breeders of pedigreed cats.

Who can and needs it

It is advisable to use hormonal drugs to interrupt estrus to offspring-producing animals, cats that have contraindications to anesthesia and surgical intervention in general (for example, with heart diseases, kidneys, etc.). Contraceptives are also given to cats who unexpectedly resume estrus after castration.

Cats in breeding

Perhaps, prolonged contraceptives are really necessary for this category of animals. The schedule of mating and resting between them implies the presence of empty leaks, and hormonal drugs such as Covinan or Depo-Provera (or its analogues) help to survive them with the least damage.

Here's how a veterinarian working with cat kennels says about it (peeped on the forum of the portal "Vetmedical"): If the animal is breeding, used in breeding, but has violent exhausting estrus, the use of hormones in adequate doses and in adequate time is justified. However, such cats are not bred from breeding at an advanced age. Well, there's no options for the operating table.

So, what happens as a result of injection:

The introduction of the drug stops the development of estrus in a cat and removes all its negative manifestations. And everyone will be happy!

Or the cat still ends up on the operating table, only under much worse circumstances. Or you will need treatment of the endocrine system.

Are there always negative consequences after using hormonal contraceptives?

No. This is roulette.

Some cats spend their whole lives "sitting" on pills and injections, and at least that (at least it seems so, since there are no visible changes).

For others, it "shoots" immediately. Or after some time (maybe in years). As luck would have it.

Otsebyatina: Do you know how many owners go to the clinic with the requirement to give their cat a hormonal injection? - A lot. Do you know how many of them do it the way they should? - Units. Almost all injections are given "when it's time", that is, during sexual hunting.

Dear cat owners! If you do not plan to have kittens, sterilize your pet immediately. This will make life much easier for both him and you. But if you have decided to fight the instinct of reproduction with the help of hormones, then please do it right! After all, there is no one but you to take care of your cat.

P.S. Is it possible for a cat to put such a prick, well, so that she does not ask for a cat? -from the application to the veterinary clinic

Yes, you can. But, first of all, if carefully. Secondly, is it necessary?

The following doses are used for cats:

<3 kg 1 ml
3-5 kg 1-1.5 ml
>5 kg 1.5-2.5 ml

Covinan is administered to animals strictly subcutaneously in the middle part of the skin fold, avoiding intradermal injections, getting into subcutaneous fat deposits and scar tissue. Before use, the vial with the drug should be thoroughly shaken, and the injection site should be treated with 70% ethyl alcohol.
