Spaying a female cat is a choice that has medical and behavioral benefits and thus, protects her health.
Why sterilize a female cat?
Each cat’s reproductive cycle is characterized by polyestrality, that is, the manifestation of heats (the estrous cycles) that occur regularly from February to October.
This is because the cat has an induced ovulation cycle i.e., her ovulation is caused by the sexual act.
Therefore, from the time the first “heats” begin, if they are not followed by mating with the male, the ovaries remain perpetually or almost perpetually in an active pre-ovulatory phase.
The direct consequence of so much heat is a "hormone bombardment" that mainly affects the uterus, breasts, and bone marrow in addition to all other tissues and organs. This continuous production of hormones can lead to the onset of serious diseases.
So many heats, so many hormones. So many hormones, so many risks.
The cat's sterilization surgery:
Spayed female cats have a longer and less disease burdened existence than unspayed female cats.
So, spay your cat to the benefit of your four-legged cat's serenity but also your own.
