What is removed from cats when they are neutered? - briefly
When cats are neutered, the testicles and sometimes the epididymis are removed in males, while in females, the ovaries and uterus are typically removed. This procedure is done to prevent unwanted behaviors and health issues associated with hormonal changes.
What is removed from cats when they are neutered? - in detail
When cats are neutered, what is removed depends on whether the cat is male or female. For male cats, the procedure is called castration, and the testicles and often the epididymis are surgically removed. The testicles produce sperm and testosterone, a hormone that contributes to male behavior such as marking territory and aggression. Removing them prevents reproduction and can help mitigate these behaviors. In some cases, the vas deferens may also be removed.
For female cats, the procedure is called spaying or ovariohysterectomy, where both the ovaries and the uterus are surgically removed. The ovaries produce eggs and hormones such as estrogen and progesterone, which regulate the reproductive cycle and prepare the body for potential pregnancy. Removing the ovaries stops the heat cycles, prevents unwanted pregnancies, and reduces the risk of certain diseases like pyometra (a uterine infection) and mammary cancer. The uterus is also removed to prevent complications that can arise from leaving it in place, such as uterine stump pyometra or ovarian remnant syndrome, where small pieces of ovarian tissue may remain and continue to produce hormones.
In both male and female cats, the neutering procedure involves making a small incision, removing the specified reproductive organs, and then closing the incision with sutures or surgical glue. The cat is typically put under general anesthesia for the procedure to ensure they remain still and do not experience any pain during the surgery. After the procedure, cats are usually kept overnight at the veterinary clinic to monitor their recovery before being sent home.
