Is my Cat too Old for Surgery? (Neutering)

It is thought that surgery is beneficial before a cat reaches the age of 5 months, i.e. when it achieves sexual maturity.

Generally speaking, as a cat gets older, its capacity to survive surgery decreases. This is related to the slower rate of metabolism in elderly cats and changes in their body composition.

When it comes to cat surgery, there are three available options: Early or pediatric spay/neuter is conducted between the ages of six and eight weeks. At five to six months, a standard spay and neuter procedure is performed. Finally, the best option is to wait until after the first heat, when the child is between eight and twelve months.

The most common surgery in the case of cats at a young age is neutering. It can not be done at old age.

What exactly is Neutering?

Orchidectomy is the term used to describe the procedure of neutering or castration of male cats. The treatment is performed under general anesthesia, and an incision is made along either side of the scrotal sac to allow for the removal of each testicle, which can be either excised or removed altogether. In most cases, external sutures will not be required. In males, both testicles descend into the scrotal sac before birth from inside the abdominal cavity through the inguinal canal located in the lower abdomen. Cats with partial scrotal sac descent may have one or both testicles that do not entirely descend into the sac and may either remain in their abdomen or be kept anywhere along their inguinal canal path to the sac.

These cats are classified as cryptorchids, and a more comprehensive surgical procedure will be required to locate and remove their testicles. It is essential to note that if these retained testicles are not removed, they will continue to generate hormones, and the cat will behave in a manner consistent with an intact male cat. A vasectomy is not performed on cats because this treatment merely sterilizes a cat and does not prevent the generation of male hormones in the cat. Both sterilization and elimination of male hormones are responsible for the positive behavioral effects associated with castration.

Why has your Cat Surgically Treated?

There are various advantages to having your cat medically neutered by your veterinarian, and you should discuss them with your veterinarian. You should have your pet surgically neutered since it is one of the most critical health decisions you may make for his or her long-term health and well-being.

An ovariohysterectomy, often known as a spay surgery, is a medical treatment that removes the female reproductive organs, including the ovaries and the uterus, by an incision in the belly. Sometimes (though not frequently), only the ovaries are removed (ovariectomy). When you neuter a male cat (castrate him), you remove both testicles by small skin incisions in his scrotum, the sac containing both testicles. When addressing the technique of neutering a male cat, the term “neuter” is sometimes used instead of the term “castration.” It is possible that the testicles will not descend entirely into the scrotum during the tom operation (cryptorchid), in which case a new surgical procedure is required. During the physical examination, your veterinarian will uncover the problem and notify you of the need for an alternative surgical procedure to correct it.

When Is It Time to Neuter Your Cat?

Most veterinarians recommend that your cat be neutered when he or she is around 5-6 months old, although it is never too late to neuter your cat if he or she is in otherwise good health. Some female cats begin their menstrual cycles as early as five months of age; thus, keep young female cats indoors until the procedure is completed. Many humane shelters are now doing early spaying and castration before pet adoption, and there have been no reported negative long-term impacts as a result. This technique contributes to reducing the pet overpopulation problem, which is one of the most compelling reasons to have your cat neutered.

The hormones that stimulate reproductive behavior in cats are removed when cats are neutered. Other than the inability to reproduce, this has several advantages, including the following:

  • Spaying, your female cat, will prevent her from going into heat in the future (estrus). Female cats in good health come into the heat numerous times throughout the year. Heat can last anywhere from three days to nearly three weeks, and she will cycle into heat each two to three weeks until she becomes pregnant. She may exhibit excessive screaming and wailing during her heat cycle, rolling around on the floor, and rubbing up against people, animals, and things. When she becomes excited, she may raise her tail and spray urine all over the place. She may exhibit only extremely faint or no indications at all. Male cats will be drawn to the house, and she may attempt to escape by running outside. When female cats contact male cats, they may get pregnant or give birth to unwanted kittens and develop wounds and diseases. Uncontrolled reproduction year after year will also put a strain on the mother cat’s energy reserves. Having two or three litters per year is not uncommon among traveling cats. This drain on her physical reserves can cause the female to become depleted if she is not given the time to recuperate between her nursing and pregnant periods.
  • A female cat’s risk of getting mammary gland tumors later in life will be significantly reduced if she is spayed early in life. This is a crucial reason to have your cat neutered at the suggested age of 5-6 months or as soon as possible after that. Eighty-three percent to ninety-three percent of mammary gland tumors in cats are malignant. Spaying also lowers the likelihood of developing ovarian cancers later in life.
  • In addition, spaying will reduce the likelihood of a female cat acquiring infections of the uterus (womb) and atypical uterine reactions (cystic endometrial hyperplasia), promoting diseases like endometritis and pyometra be life-threatening conditions.
  • Castration will reduce inappropriate tomcat habits such as urine spraying on walls and furniture to “mark” his territory, as well as other undesirable activities. Following castration, it has a 90 percent chance of eliminating urine spraying in male cats still in heat.
  • In addition, castration will reduce a male cat’s propensity to roam outdoors in search of a female cat in heat. He will be less likely to be involved in car accidents, dog attacks, wildlife encounters, or cat battles due to this. The danger of infection with contagious viruses that are primarily transmitted by saliva, such as feline immunodeficiency virus, feline leukemia virus, rabies virus, and other infectious agents, will be reduced due to this procedure. He will have more minor wounds and abscesses as a result of this. The reduction of his outside roaming activities may also promote harmony and quiet in the surrounding area.
  • Castration will ultimately reduce the possibility of a male cat getting testicular cancers.

Numerous pet owners are anxious that their cats would gain weight due to having their cats neutered. This is not a suitable excuse for delaying the neutering of your cat. Though your cat can gain weight, feeding a balanced diet, avoiding overfeeding, and ensuring that your cat gets plenty of activity can help keep your cat’s weight at an appropriate level. Regular checkups and weight checks with your veterinarian will help you maintain your weight loss goals and stay on track. Neutering your cat is the greatest option for your cat’s long-term health and is required to help curb pet overpopulation in the United States.

Reasons for Early Spay/Neuter

It is never too late to get your cat fixed. There are numerous health benefits linked with neutering, which can help prevent difficulties in older felines. Kittens are often neutered when they are young when their bodies are at their healthiest and strongest; however, older cats are usually well with the treatment.

Reduce Health Problems

The results of a risk-benefit analysis are used to decide whether or not to execute any medical or surgical procedure on a particular patient. Are there any medical advantages to spaying cats before they reach the age of five months? According to epidemiologic studies conducted in 1981 and 2005, cats that have been spayed before their first heat cycle have a much reduced incidence of mammary neoplasia than cats that have not been fixed. Because mammary neoplasia is the third most common cancer in cats, up to 97 percent of mammary tumors in cats are malignant. This finding is significant because the median survival time for cats with mammary neoplasia is typically less than that of cats one year, and this finding is particularly effective. 5, 6 Spaying or neutering a cat will, without a doubt, remove disorders of the uterus, ovaries, and testicles. Spaying cats older than one year has not been found to lower the incidence of mammary neoplasia; however, removing the cat’s ovaries and uterus can prevent pyometra and ovarian neoplasia from developing.

Territorial Behavior Has Been Reduced

Feline spraying alone is a significant motivator for many people to get their pets neutered, as the spray smells terrible and is difficult to clean up. Male cats are more likely than female cats to roam, fight, and mark their territory with urine markings, but cats of either gender can indulge in these undesirable behaviors. Neutering your cat while he is young can prevent him from engaging in these habits in the first place.

Other Behavioral Modifications

You shouldn’t be concerned about your cat becoming lazy, obese, or dull following the neutering procedure. The surgery itself does not cause these adverse effects, albeit it does impair your pet’s desire to exercise due to the process. While approximately one-fourth of cat owners believe that neutering their cat has made him more relaxed, the majority of cats do not demonstrate any apparent personality changes after the operation. Older cats may require a few days to get back to their usual selves, while younger cats will return to their typical selves in a few days. If your cat has lived for years with all of its components in place, it may take a few weeks or months for her to adjust to a life with fewer hormones in the environment.

Health Consequences

Neutering is an invasive surgery, and as a result, there are some health concerns linked with the procedure. Because the surgeon must make a 2- to 3-inch incision in her tummy, the risks are higher for females than males. Since your cat is becoming older, his immune system continuously loses strength; there is a tiny probability that the wound could become infected. Young cats recover more quickly and have stronger immune systems than older cats. Older cats are also more liable to have pre-existing health problems, making the surgery more difficult and time-consuming. Your cat will be lazy when you first bring him home from his procedure, and he may even refuse to eat for a short time. This is very normal and should only last a day or two.

Containment of the Population

Every year, thousands of cats are put to death, more kittens are produced than homes available for them. To maintain population control, neutering of intact male cats is required. A single male cat can father multiple litters. Although castration will significantly lower sexual desire in most men, experienced males may continue to express sexual interest in females.


The most common behavior problem is indoor elimination in places other than the litter box for cats of any age. Cats that scatter or mark walls and other vertical home objects account for a disproportionately significant proportion of these occurrences. When it comes to marking territory, adult male cats strongly need to do so indoors and out. About 85 percent of male cats who are neutered have a reduction or complete elimination of spraying.


Whether neutered or intact, Cats can engage in fights, although most interactive aggressiveness occurs between males who are not fixed. This is a direct result of male cat competitiveness, and that intact male cats travel and protect a considerably bigger territory than neutered male cats. If these conflicts result in punctures or wounds that pierce the skin, abscesses are a common complication that occurs as a result. Male cats who have been neutered experience less fighting and abscess formation.

Roaming and Sexual Attraction

Females and neutered males have substantially smaller territories, and intact males travel far longer distances than females and neutered males. In the course of the mating season, the desire to roam may be particularly intense. Castration is effective in reducing roaming in around 90% of instances. Although neutering significantly diminishes sexual attraction in females, experienced males may persist in being attracted and mate with females after being neutered.

Changes in the Physical Environment

The smell of male urine is powerful and harsh. Castration results in a shift in the odor of the urine to a more typical odor. After neutering, many owners report that their intact males become considerably cleaner, less odorous, and better self-groomers due to the procedure. Abscess creation as a result of fighting is substantially less common. However, some secondary sexual features, such as the overproduction of tail glands in the condition known as “stud tail,” can be significantly improved due to fighting.
