Why are a cat's ovaries removed during sterilization? - briefly
A cat's ovaries are removed during sterilization to prevent reproduction by eliminating the source of eggs and halting the production of reproductive hormones. This procedure ensures the cat cannot go into heat or become pregnant.
Why are a cat's ovaries removed during sterilization? - in detail
The removal of a cat’s ovaries during sterilization, a procedure known as ovariectomy or, more commonly, ovariohysterectomy, is performed to prevent reproduction and eliminate the production of reproductive hormones. This process is essential for controlling the feline population and addressing health and behavioral concerns. The ovaries are responsible for producing estrogen and progesterone, hormones that regulate the estrous cycle, also known as "heat." By removing the ovaries, the cat no longer experiences these cycles, which reduces behaviors such as yowling, restlessness, and attempts to escape in search of a mate. Additionally, the procedure significantly lowers the risk of reproductive-related diseases, such as ovarian and uterine cancers, pyometra (a life-threatening uterine infection), and mammary tumors, which are often hormone-dependent. Leaving the ovaries intact while removing only the uterus would not achieve these benefits, as the cat would continue to produce hormones and experience heat cycles. The removal of the ovaries is a definitive and effective method to ensure the cat cannot reproduce and to promote long-term health and well-being. This surgical approach is widely practiced in veterinary medicine due to its safety, efficiency, and comprehensive benefits for the animal’s overall health.
