The most troubling question among cat owners - why do pet cats need to be neutered?

 8:46am, 10 October 2025

For many novice cat owners, they always struggle with whether to have their pets neutered or not. Some people think that neutering a cat is cruel, but others think that they don’t want to leave a mutilated cat. In fact, neutering is a decision made to prevent excessive breeding of cats, leading to abandonment, and to keep the cats healthy.

1. The benefits of sterilization

Some people think that sterilizing pets is cruel and inhumane. Think about it, even people have to control their fertility, so letting pets also control their fertility is not inhumane. Besides, is it more humane to irresponsibly allow pets to reproduce freely, resulting in an overpopulation of animals, which will lead to a large number of pets being abandoned, wandering, and dying early due to hunger and disease? Or is it more humane to control the number of pet breeding, be a responsible pet parent, and give them a stable, happy, and high-quality life?

1. First of all, reduce the number of unnecessary pets that no one needs, thereby reducing the number of stray pets and preventing pets from suffering a tragic fate;

2. Cats will no longer get lost due to heat.

3. Neutering surgery can extend the life of your pet. This is because constant and excessive reproductive activities will accelerate the aging of body organs and shorten the life span of pets.

4. Neutering surgery can make your pet live a healthier life and reduce the chance of illness. Studies have shown that sterilization can reduce the chance of female pets suffering from uterine, ovarian and breast cancers, especially when the female animal has just become sexually mature and has not yet given birth. The effect is more obvious. Neutering surgery can reduce the chance of testicular cancer in male animals and reduce the incidence of prostate disease.

5. Sterilization surgery can change the pet's personality, reduce or completely change the pet's habits of wandering, fighting, peeing everywhere, and howling, thereby greatly reducing the chance of being lost or injured, and being infected with diseases. At the same time, the pet becomes more affectionate, willing to be with people, and has a close, docile, and trainable relationship with its owner. More importantly, the life span of pets that do not wander out is much longer than that of pets that often wander around. Cats can live for more than 16 years (16 years is equivalent to 80 years of human age, and 20 years is equivalent to 96 years of human age), and dogs can live 14-15 years (80-96 years of human age).

2. Time for sterilization

Generally, cats can be sterilized when they are six months old and weigh more than six pounds (it is recommended to do it after the cat reaches sexual maturity or adulthood). In addition, sterilization is not recommended during the estrus period. Elderly cats can also do it (depending on the cat’s physical condition).

3. Special reminder!

1. Cats (especially female cats) will increase their food intake within six months after sterilization, and some cats will gain weight rapidly. During this period, owners must pay attention to controlling the cat’s diet. Cats that are too fat are prone to "obesity disease". The fatter the cat, the better.

2. For sterilization surgery, it is recommended to do it when the weather is cooler. When it is hot, you need to pay attention to heat dissipation to avoid wound infection and inflammation.

3. As for the approximate cost of the operation, you need to see the hospital. Each hospital’s costs and surgical options are different, so you can consult your local hospital for details.

4. Manifestations of pets in estrus

For cats, estrus is a very easy phenomenon. Generally speaking, it will be more obvious in spring and autumn. If the female cat at home does not have frequent contact with the outside world, in theory, it will go into estrus once every six months. However, if it has the opportunity to contact male cats, it may go into estrus every month. When cats are in estrus, they usually wet the bed, have bad tempers, etc., or they may change their previously well-behaved life and urinate and defecate at will.

5. The necessity of pet sterilization

Experts estimate that a female cat and her "offspring" can produce 420,000 kittens in 7 years. What a shocking number! If you don't plan to raise your cat's next generation, spaying or neutering is a sign of responsibility for them.

Secondly, sterilization surgery can also make pets live healthier.

Sterilization surgery can reduce the probability of pet diseases. Studies have shown that sterilization surgery can reduce the chance of female pets suffering from uterine, ovarian cancer and breast cancer. It can reduce the chance of male animals suffering from testicular cancer, reduce the incidence of prostate disease, and can also help pets live longer.

Neuteration surgery can also change the pet's personality, reducing or completely changing the pet's habits of wandering, fighting, peeing everywhere, and howling. Moreover, neutered cats will no longer be in estrus, so the troubles during estrus will disappear.
