Part of being a good cat parent is doing things for your kitty that suck for them now but benefit them in the long term. Cats aren’t super great at listening to reasoned explanations about why you take them to the vet, don’t share your food with them, or keep the door to the garage closed.

It can be scary for both of you, but neutering your male cat or kitten trades a few days of discomfort for life-long rewards. Even though this is a routine procedure, there may be some unexpected changes after surgery, especially if you haven’t been through it with a cat before.

What is cat neutering?

Neutering is a sterilization procedure that removes a male cat’s testicles. It’s a very simple concept: no balls, no babies. In most cats, this is a very quick procedure that is done under anesthesia with two small incisions into the scrotum. These small incisions usually do not require sutures, which is great because cats hate those things.

In some cats, one or both of the testicles do not descend into the scrotum like they should. This is called cryptorchidism. In cryptorchid cats, a more involved surgery is needed to get to the testicles. This can often involve an incision into the abdomen to find and remove them.

What are the benefits of neutering?

Thebiggest benefits of neutering that you’ll see are behavioral, but there are other advantages to the procedure as well. Sterilization prevents your cat from breeding. There are already plenty of great cats and kittens in animal shelters waiting to be adopted, and you don’t need your male cat out there making more. There are also health benefits related to a decreased risk of testicular cancer (obviously) and an overall longer lifespan in neutered cats.

What behavioral changes are expected after a male cat is neutered?

Reduced Aggression

Testosterone drives a lot of the more annoying behaviors of male cats. Removing the testicles removes the biggest source of testosterone from the body. In free-roaming cats,aggressive behaviors like fighting and vocalization were reduced after neutering. This helps with indoor cats too. It’s no fun waking up to a blood-curdling yowl from your cat because something dared step into the yard he’s guarding through the window.

Reduced Roaming

Without the effects of testosterone, cats are much less likely to try to force their way outside and get in trouble. After neutering, cats’ generalactivity level decreases, and they’re much happier to sit around and enjoy the day.

Reduced Spraying

Intact male cats want to lift their tail and mark everything with urine to claim it as their own. And their pee stinks. It stinks in a way that lingers in your nose and sticks to your clothes. No one wants their house to smell like that, and neutering fixes that problem quickly.

Improved Litter Box Habits

Less pee on your walls and furniture means more pee in the litter box. Neutered cats are much more content to follow your desire to not have them urinate on everything you own. Fewer surprise wet spots lead to a much happier relationship overall.

Increased Affection

Neutered cats aremore affectionate with their families and less feisty with any other cats they live with. Intact cats can still be plenty friendly, but why choose less kitty love when you can have more?

How soon will I notice changes in my male cat’s behavior after neutering?

Testosterone takes a month or two to leave the system, so some behaviors and odors can persist through that time. Despite this, some results of hormone changes, such as increased appetite, can be seen as soon as three days after surgery. Generally, you can expect younger cats to calm down (well, calm for a kitten) more quickly, while older cats may have some habits that take longer to go away.

How to recover a male cat after neutering?

The best bet is always to follow the advice of the veterinarian who did the procedure. They will know what type of procedure was done, if there were any complications, and what medications your kitty has been given. Although every cat and every procedure are different, some general advice can be followed.

How to Care For Your Cat After Surgery

Cats should take it easy after surgery. This is often easier said than done, especially when kittens are involved. Your vet may recommend confinement to a large crate or a small room without furniture to jump on. The big thing is to prevent them from traumatizing their surgery site and causing bleeding.

After surgery, cats will often go home with an e-collar that should be kept on until the incisions are healed. Cats hate wearing cones and are very good at twisting themselves into knots to wiggle them off. Try to keep the cone in place and watch your cat closely to make sure he’s not getting into trouble and licking his incision. Watch the scrotum or the incision for any signs of discomfort, redness, swelling, or discharge and report any issues to your vet.

Common Complications of Neutering

Fortunately,post-operative complications are rare after neutering. Bleeding from the surgery site or swelling of the scrotum is possible. Infection can occur after any incision but is uncommon, unless the cat licks at the area. Although surgical complications are infrequent, hormonal changes can cause issues if you’re not vigilant.

The most common complication of neutering a cat is weight gain. Because of hormone shifts after being neutered, male cats often begin to try toeat more after being neutered. This can lead to rapid weight gain, with adult cats in studies gaining about20-28 percent of their body weight within six months after surgery. This is hard on joints and can increase the risk for diabetes and heart disease.

Weight gain can be avoided by getting your cat used to set meal feedings (rather than being free-fed) before surgery and monitoring their weight and body condition every two weeks after surgery. Staying vigilant about your cat’s weight early in life will make keeping them trim and lean in their later years much easier.

Any surgery is a big deal, but neutering is a routine procedure that has many benefits that will improve life for both you and your cat. Discuss the right time to have your male cat neutered with your veterinarian.
