Neutering and spaying in cats. Consequences

Spaying cats  is a necessary method of controlling feline overpopulation. In males, the procedure may also be called castration , while removal of the ovaries in female cats may be called spaying or ovariohysterectomy .

The neutering and spaying procedure can have short- and long-term secondary effects and consequences :

Short-term health consequences and side effects

The feline castration procedure is simple and can have minimal side effects.  The cat may experience pain after surgery, but the vet will prescribe appropriate pain medications.

Neutering is an invasive operation , so some health risks are associated with it. The risks are greater for females than for males, because the surgeon must open a 2 to 3 centimeter incision in her belly. As your cat ages, her immune system gradually loses strength, so there is a small chance that the incision will become infected. Young cats heal faster and tend to have stronger immune systems. Older cats are also more likely to have existing health problems, which can complicate surgery. 

Your cat will be lethargic from the surgery and anesthesia when you bring him home after his operation and may refuse food for a time. This is normal and should only last a day or two.

Other postoperative side effects of castration surgery include redness and swelling of the surgery wound, infections (which can be treated with antibiotics), and scarring.

In rare cases, the surgery may not be successful and the vet will need to perform a second intervention. 


Weight gain

Weight gain can be a long-term side effect of neutering cats . After surgery, the cat will no longer waste time looking for a mate to mate, so it will be more sedentary. If the cat eats the same amount of food, it is most likely that he will gain weight.

You should talk to your vet and make some changes to your cat’s diet; you should reduce their calorie intake, without affecting the  amounts  of essential nutrients your pet needs.


Character changes in spayed cats

Don’t worry about how neutering can affect your cat’s character. Being spayed should make your cat calmer . You know that unspayed cats , especially males, are more aggressive than neutered ones, especially if they spend a lot of time away from home.

The characteristics of your personality will not change after neutering or sterilization . If your cat is active, playful and affectionate, it will remain that way after neutering, so you can rest easy. Ultimately, there are no behavioral changes in cats.



Lack of physical activity

Since the cat will no longer be interested in mating, it will spend more time indoors. Male cats tend to become aggressive when fighting over a female or territory. After being neutered, the cat will be less  aggressive  and sleep longer.

Lack of activity can lead to obesity.

You need to get your pet used to doing new indoor activities to help him  stay active . Start different games, get some toys and encourage your pet to be active.


Delayed cat growth

Stunted growth can be a side effect of the castration process, but it is rare. This can happen only if the castration is done too early. Consult your vet to determine the optimal time to neuter your pet. The best time to sterilize cats is just before they reach sexual maturity (before the first heat cycle in females).



Cystitis or urinary infections are common in neutered cats. In very rare cases, male cats can experience urinary blockages. To avoid this, your vet may recommend a wet diet and you should also try to increase the cat’s water intake.





There are really very few negative effects as a result of neutering your cat, it provides more benefits than harm to your pet. It is an operation of twenty-five or thirty minutes in a female and about fifteen in a male, which is performed under general anesthesia, so the animal does not suffer pain, and that same day they can return home.

Recovery is just as fast . The next day he will practically be living a normal life and our pet will be “the same” again in a couple of days. In addition, with absorbable sutures, there is no need to worry about stitches, and except for the administration of a mild antibiotic (pediatric) to prevent wound infections, no cures are necessary.

Neutering and spaying will help your pet become a better companion and live a longer, healthier life.

You contribute by avoiding inconvenience to the neighbors (the heat of the females can be very annoying) and you avoid the uncontrolled proliferation of street colonies.

They will stay at home very happy, whether it is an indoor or outdoor cat. Without spaying, the male will wander, fight, bleed, and the female will attempt (and generally succeed) to escape, while attracting other cats, howling into your home or garden.

Males spray urine and make your garden and home smell really bad if they aren’t neutered. Cats will go into heat and be excruciatingly noisy every 2 to 4 weeks if they are not spayed. The cats you attract will be just as loud.

It is simply not worth having an uncastrated cat, and if yours is a female very soon you will have many uncastrated cats.
