For what you need sterilization of cats
Sterilization — intra-cavity surgery to remove ovaries, after which the cat is forever denied the opportunity to have offspring. It would seem that if the cat lives at home and doesn’t go out, this operation could not be done. But this is not the case — every estrus of an animal that happens once every 3-4 months will be accompanied by changes in its behavior. A cat can scream at night or even start using instead of the usual tray your shoes and clothes to declare its readiness for mating. She experiences physical discomfort at this time and tries to eliminate it in every way available.
Taking hormonal drugs that prevent ovulation in cats can provoke cystic and cancer diseases.
In the fact that sterilization is necessary, no one argues, the question is when it is best done, since it is a violation of the hormonal background, which of course has a direct impact on the physical condition and health of the animal.
At what age to sterilize a cat
In the West there is veterinary experience of sterilization of cats at the most “tender” age — at 7-8 weeks before the kitten enters puberty. The surgery, which is done at such an early age, allows to reduce the likelihood of complications, and the postoperative sutures in this case heal faster. But the sterilized cat is yet to have time to form, to reach physical and sexual maturity before these irreversible hormonal changes were produced. Because the process of genital development is interrupted, this is reflected in the functions of the hypothalamus that determines the animal’s behavioral responses. Therefore, the cat’s behavior can become unpredictable, and, moreover, hormonal disorders provoke failure in physical development as well. Such an animal may have a disproportionate structure — too small a head on an excessively large body.
You can’t sterilize an animal during estrus — there is too great a risk of complications.
If a cat is sterilized after the first birth or at the age of 1.5 or more, the animal has an increased risk of breast cancer. If after the first birth such probability is 8%, after the second it increases already up to 26%. In the case that the cat is old enough, sterilization will have no warning effect. Most veterinarians tend to believe that the most optimal term for sterilization of cats is the period before the first estrus. In this case, the risk of breast oncology is only 0.5%.
