Male cat's neutering (castration)

Suddenly I remembered that we need to find a male cat for neutering demonstration next week. I have posted female neutering before because we have seen it (not practical) but now let's do a little study for castration.

Why neutering is good???

The main reason to neuter a male cat is to reduce the incidence of objectionable behaviors that are normal in the feline world but unacceptable in the human world.

ROAMING More than 90% will reduce this behavior with neutering. Approximately 60% reduce this behavior right away.

FIGHTING More than 90% will reduce this behavior with neutering.Approximately. 60% reduce this behavior right away.

URINE MARKING More than 90% will reduce this behavior with neutering. Approximately 80% reduce this behavior right away.

Another reason to neuter a male cat has to do with the physical appearance. A cat neutered prior to puberty (most cats are neutered at approximately age 6 months) do not develop secondary sex characteristics. These include a more muscular body, thickenings around the face called “shields,” and spines on the penis.

When to do castration?

Male cats are usually neutered between 5 1/2 and 9 months of age, before habits such as spraying urine are started.


Castration procedure


Lets review anatomy!



This is errr....testes!


The testicle is covered with a fibrous cover called the tunica vaginalis. In the cat, this covering is usually removed so as to perform what is called an open castration. If the tunic is left intact and simply tied, this would be a closed castration.


When the tunica vaginalis is open (by small incision), this is what we will see




The Testis or Testicle where sperm and male hormones are made (flesh pink in the diagram).The epididymus, which stores sperm and serves as the beginning tubular system sperm must travel through.The epididymus unwinds into the straight ductus deferens (also called the vas deferens), the white tube on the right in the diagram. The deferential artery and vein are very small but accompany the ductus deferens.

The much larger blood vessels adjacent is called the pompiniform plexus or vascular cord. This structure serves as a cooling system for the blood traveling to the testicle. Sperm do not live long at normal body temperature, and thus must be housed externally in the scrotum and receive cooled blood. The pompiniform plexus (red in the diagram) is made up of the spermatic artery and vein coiled around each other.



Meet Comel our volunteer! Comel is about 1 year old
Weight around 3 kg

Comel is anesthetized with isoflorane gas delivered via a face mask. Injectable anesthesia could alternatively be used. Before anesthetize, tom is fasted overnight so that it wont vomit at time of recovery. Analgesic drugs may be given to control postoperation pain


Once anesthetized, Comel is positioned on his back and the technician gently clips the fur from his scrotal area.



The scrotal area is exposed



Comel’s scrotal area is disinfected with surgical scrub and the procedure begins



With gentle squeezing of the scrotum and a small incision from the scalpel, the first testicle is exposed.



The tunica vaginalis is opened with another small incision to reveal the testicle and its associated cords.



The ductus deferens is the structure on the left, while the pampiniform plexus is on the right.



The ductus deferens is separated off the epididymus with a little tug from the clamp



The ductus deferens and pampiniform pemplex are tied together in a square knot.


The cords are cut on the testicle side of the knot.



And now for the other side...
The blade is used to incise the scrotum directly over the testicle. The testicle is removed from the incision.



The tunica vaginalis is incised and the testicle and its associated cords appear. The tunica vaginalis is the small bundle of tissue at the point of the clamp. The pampiniform pemplex is on the left and the ductus deferens is on the right.



The clamp is used to pluck the ductus deferens off the epididymus.



The two cords are tied together in a square knot.



The cords are cut on the testicle side of the knot.



The knot is replaced back in the scrotum. The incisions are so small that stitches are not required.

Confuse?? check out this cool vid :)






Keep the cat quiet and indoors for approximatly two weeks after he returns home from the hospital to allow him to heal. Do not allow him to be excessively active and prevent him from "rough-housing."

Monitor the incision daily for signs of redness, swelling or discharge. Do not allow your pet to lick or chew at the incision. If you find it is impossible to stop your pet from doing this, you should obtain an "Elizabethan" collar that is placed around the neck to prevent access to the incision.

It is a good idea not to bathe the kitten until the incisions have healed 10-14 days from the time of surgery.Skin sutures, if present, will be removed in 10 to 14 days. If the castration was performed for reasons other than to prevent reproduction, further treatment and/or monitoring may be necessary.
