Video: How To Prevent Unwanted Pregnancy In A Cat?
One of the most pressing biological problems of the modern city is stray dogs and cats. This huge four-legged army is distinguished by its ability to continuously increase its numbers for two reasons.
The first is intensive reproduction. A simple calculation shows that within 6-7 years a cat and her offspring can give birth to about 350,000 kittens (provided that all those born survive and take an active part in reproduction). The second source of recruiting for this army is the lost and abandoned animals.
Sadly, the most effective measure for limiting the number of stray cats is their destruction. Many pet owners follow the same path when unwanted offspring appear.
Are there humane methods of population control? Definitely yes. And with their help you can save many unborn babies from euthanasia yourself.
The most radical methods are to neuter the females and castrate the males. In both cases, infertility is achieved by surgical removal of the reproductive organs. This operation is performed under general anesthesia and does not involve serious complications. In addition to the main goal, sterilization and castration can solve a number of other tasks, including:
- increase the life span of an animal by an average of 5 years;
- eliminate unwanted forms of behavior (aggressiveness, nervousness, etc.); this effect is especially important in the case of cats that are in heat and marking their territory;
- prevent the development of oncological and gynecological diseases, in particular inflammation of the uterus and the accumulation of pus in it; never wheezing bitches are especially prone to this disease (pyometra); pyometra most commonly occurs in aging animals when surgical removal of a pus-filled uterus is associated with serious complications.
There is no consensus on the optimal timing of the operation: many veterinarians tend to combine it in time with the achievement of physiological maturity, while others prefer to do it as early as possible (starting from 8 weeks of age).
Removal of the uterus can be recommended not only for prophylactic purposes, but also after unwanted mating, as well as for a number of diseases (pyometra, ovarian cystosis, uterine tumors, etc.).
A long-term negative consequence of the castration of cats is a more severe course of urolithiasis, therefore, it is not necessary to include dry food and fish in the cat's diet, which contribute to the formation of stones. If the animal is already accustomed to dry food, then it should be gradually transferred to special varieties intended for the prevention of urolithiasis.
Sterilized and neutered animals are prone to obesity, which often leads to hormonal disorders, diabetes and heart failure. But this cannot be a reason for refusing sterilization or castration, since the correct composition of the diet and active daily exercise will save you from these troubles.
An alternative to sterilization is hormonal contraception. The most effective drugs are proligestone drugs (eg, covinan). This hormone inhibits the maturation of ovarian follicles, which leads to a slowdown in the estrous cycle. Bitches and cats do not develop estrus after its introduction for 5 months. If you need to get offspring, the drug is no longer used, the first estrus is passed, and the second is mated.

But if an unwanted mating has occurred, then you should not despair either. In addition to surgery, there are drugs for abortion. Timely use of such drugs as mesaline (was discontinued) , irmanil and alizin (on the 3rd, 5th and 7th days after mating) will not allow the fertilized egg to penetrate into the uterus and attach to its wall. The effectiveness of this method is 98%. However, after the use of estrogens (hormonal contraceptives), the duration of estrus increases, which increases the risk of mating again.
Recently, trials of phenyltriazole have been initiated for early abortion in small pets after mating. If they pass with a positive result, this non-hormonal drug will compete with hormonal analogues.
Significantly more complications arise with medical abortion at a later stage of pregnancy. The choice of how to prevent unwanted pregnancy is up to you. But its practical implementation should be entrusted to a veterinarian, which will solve the problem in question, without compromising the health of your pets.
