One of the most common surgical procedures we perform is a cat neuter, know medically as an orchectomy. It is performed for several reasons:

  • It minimizes roaming
  • It minimizes aggressive behavior
  • It prevents male cats from impregnating females.
  • It minimized urinating in the home (urine spraying).

Male cats are territorial and prone to fighting, which leads to serious diseases, especially viral diseases like FeLVFIP, and FIV. Neutering minimizes this fighting, helping also to cut down on these serious contagious diseases.
At the Long Beach Animal Hospital use of the laster is mandatory for all neuters. In this page we will first show you the surgery using the laser, then the traditional way this surgery is performed without the laser. The advantages of using the laser will be obvious.
Sometimes people get a jaded mindset when it comes to routine surgeries like neuters, that are performed by the thousands, especially at low cost spay and neuter clinics. It is a major surgery, and we treat it as such at the Long Beach Animal Hospital, which you will learn about in this page.
Several days prior to any surgery please bring in your pet for a preanesthetic exam and blood panel to confirm your pet is ready for anesthesia. At that time one of our doctors will go over any questions you have.
On the day of surgery we need your cat in the hospital between 7:30 AM and 8 AM. Please take away all food and water when you go to bed the evening before surgery, and do not give your cat anything to eat or drink the morning of surgery.
Our surgeon will call you after the surgery is complete and your cat is awake. It can go home in the late afternoon the day of surgery unless instructed otherwise. Please call our office at 4 PM for pickup time, you will be given written post operative instructions then. We are open in the evening if you need to pick up later.

Pre-anesthetic preparation is important in every surgery we perform, no matter how routine. all of our neuters receive a physical exam prior to surgery. After this exam will we draw a small amount of blood for an in-hospital pre-anesthetic test. When everything is in order we will give a sedative. This will calm the pet down and make the administration of the actual anesthetic, along with post operative recovery, much smoother. Once a pet is anesthetized, prepared for surgery, and had its monitoring equipment hooked up and reading accurately, the surgery can begin. Cat neuter surgery is a short procedure, and only a small amount of anesthetic is needed.

This is a sterile surgery, and our surgeon starts the pre-surgical process by using special soap to clean his hands


While our patient is being anesthetized our surgeon is already in our surgical suite setting up instruments. Our surgeon is ready to start before our patient is at a proper plane of anesthesia. Once the anesthetist gives the green light the surgery starts immediately. We want our surgeon waiting for his patient, not the other way around.  All of this is to minimize anesthetic time.


We keep a close tab on important physiologic parameters for all of our surgeries. Monitors like this give us an early warning of an impending problem.

This machine monitors:


Heart Rate

Heart rhythm

Oxygen saturation

Carbon dioxide level

Respiratory rate


In addition to our monitoring equipment our anesthetist stays “hands on” in monitoring important physiologic parameters



In general, neutering males cats is a straightforward procedure. Most cats have both testes in the scrotum, making them readily accessible by a scrotal incision. We do not suture the scrotum after the procedure since it heals very rapidly by itself.

In this picture a small incision has already been made in the scrotum with the laser, and the testicle is visible.


Our surgeon has the testicle in his hand which allows visualization of all the internal structures. You can visualize the white and glistening vas deferens at the top of the picture going from the body on the right to the testicle on the left. The vas deferens will be used to tie off the blood supply to the testicle.


Due to the small size of the blood vessels we can use the natural anatomy of the testicle to prevent bleeding when we remove the testicle. The black arrow points to the knot in the vas deferens made by the surgeon. After several more of these knots are applied the testicle at the far left will be cut off.


Another technique to tie this knot involves the use of a hemostat. This picture shows the beginning of the knot.


After the vas deferens and blood supply are wrapped around the hemostat they are then passed through the center.


Here is the final appearance after the knot has been completed.

At this point anesthesia is stopped and it is moved to recovery to be monitored by our technicians.


When fully awake we will call and let you know.


On occasion both testicles are not in the scrotum. This means that one of them is in the abdomen or in the inguinal canal, which is the passageway through the body wall into the scrotum. Either way, we have to find this testicle and remove it because it will continue to secrete hormones and can potentially become cancerous.

The skin has already been incised and our surgeon is preparing to enter the body cavity. The white glistening structure visible is the section in the center of the abdomen where the abdominal muscles and their tendons meet. It is called the linea alba. We make the incision here due to minimal blood supply and good holding power for sutures


The testicle is not the only thing that resides in the abdomen. This is a picture of the urinary bladder (we hope you didn’t think it was the testicle!) that bulged out of the incision in the abdomen. Obviously, it can interfere with the surgery when it is this full with urine, so we remove the urine before proceeding further.


Testicles that reside in the abdomen are very small because they have atrophied (shrunken in size) due to lack of use. They can be quite difficult to find, and necessitate careful exploration of the abdomen. The black arrow points to the atrophied testicle.


In this case we use suture material to prevent bleeding. The black arrow is still pointing to the testicle to help keep you oriented.


This picture is from another surgery. We have already removed a normal testicle from the scrotum and an abnormal testicle from the abdomen. You can see the difference in size and shape

When the surgery is complete we sew up the incision in the muscles and skin, and give a medication for pain. Once the hair grows back it is impossible to tell if surgery was performed.

Laser Surgery

Using the laser has many advantages over using a scalpel blade. These include negligible bleeding during the procedure and post operative pain. We can use the laser to make an incision in the scrotum, which makes the healing process much more comfortable. Our Laser Page has detailed information on the use of the laser for various surgeries.
