A Photographic Guide to Early Age Male Kitten Neutering Procedure
At the shelter where I work, male kittens over 800g and under 1kg (one kilogram) in bodyweight (usually
6-10 weeks of age - i.e. early age neutering) are desexed very quickly and atraumatically
using the following neuter procedure. The whole neutering procedure, excluding anaesthesia
induction and skin preparation, takes around 30 seconds

EARLY AGE KITTEN NEUTERING PROCEDURE STEP 1:
Image 1: The kitten's scrotal sac and groin regions are shaved free of hair (fur) and the
bare skin is scrubbed in an antiseptic, antibacterial solution (chlorhexidine scrub and alcohol) prior to surgery.
This pre-surgical skin preparation reduces the amount of bacterial contamination that is present
on the skin prior to the first incision being made.

EARLY AGE KITTEN DESEXING INSTRUMENTS.
Photograph 3: Only a new 15 scalpel blade and a pair of mosquito hemostats (also called "mozzies"
or artery forceps) is needed for this procedure. These instruments are placed in pink
antibacterial chlorhexidine solution when not being used, to keep them free of bacterial contamination.
Image 4: The hemostats or artery forceps are clamps which are used to crush tissues (e.g. blood vessels)
and occlude bleeding blood vessels. This crushing action causes the testicular blood
vessels supplying the cat testes to spasm, such that they will not bleed when the testicle is torn away.
Only one set of instruments is used for each kitten surgery. This reduces the spread of blood-borne
infectious diseases like FeLV (feline leukemia virus), FIA (feline infectious anaemia - Mycoplasma hemofelis)
and FIV (feline immunodeficiency virus - feline AIDS) between kittens.
EARLY AGE KITTEN NEUTER PROCEDURE STEP 2:
The skin incisions.
Picture 5: Scalpel incisions are made in the scrotal skin directly over each testicle. Bleeding
is very minimal.
EARLY AGE MALE KITTEN NEUTER PROCEDURE STEP 3:
Images 6 and 7: After the skin has been incised with the scalpel, each side of the
scrotal sac is squeezed so that the testicle (the pink ball seen in the images above)
contained inside pops out, ready for removal.
EARLY AGE MALE KITTEN NEUTERING PROCEDURE STEP 4:
Clamping of the testicular blood supply.
Pictures 8 and 9: The pink testicle is pulled upwards (away from the young kitten's scrotal sac)
and hemostat clamps (mosquito hemostats) are placed/clamped around the testicular blood vessels and spermatic
ducts. These clamps crush and traumatise the testicular blood vessels, causing them to
spasm and occlude when the testicle is removed, thereby preventing excessive post-surgical
EARLY AGE KITTEN NEUTER PROCEDURE STEP 5:
The testicle is torn away from the hemostats.
There is no real image for this, it happens so fast. Basically, the hemostat is left in place and the testicle
is given a firm tug, severing the testicle's spermatic cord and blood vessel supplies.
The hemostat is then released from the severed blood vessel stump (this stump is crushed
and should not bleed).
THE END RESULT - COMPLETE FELINE NEUTERING.
Photo 10: This is an image of the kitten's scrotum immediately after surgery.
It is typical for a small amount of blood to ooze from the incision lines immediately after desexing surgery.
This is seldom ever a life-threatening problem and only lasts a few minutes.
The only time that excessive, life-threatening bleeding would ever be a problem
would be if the kitten had some sort of bleeding disorder that was undetected
prior to surgery (e.g. rat sac poisoning, hemophilia, Hagemann-factor deficiency,
platelet deficiency and so on) or if the kitten was greater than 1 kilogram in bodyweight.
Cats greater than one kilo need to have their blood vessels tied off (see section 4 of
our feline neutering page for illustrations) prior to removing the testes.

Please note that this surgical technique for <1 kilogram early age male kitten neutering is only what
we use in our own shelter (it has been in use for more than the last five years).
We do not seem to have encountered any problems with this technique. Other clinics
and veterinarians may disagree with the technique illustrated on this page, in particular
the failure to tie-off the testicular blood supply. We understand this and reiterate that
it would never be used on a kitten greater than 1 kilogram or less than 800 grams in body weight. As I said before,
we haven't encountered any problems with it as an early age neuter procedure.
To all the pet owners reading this page: this page is designed to give you a visual
idea of what early age feline neutering procedures might look like. It is NOT an instructional
manual for you to try this surgery at home on your own pets! Veterinary expertise and general
anaesthesia is required to perform this desexing procedure - performing it on a conscious patient
would be considered cruel and might well result in the death of your pet.
