the average is about 6 months for female and almost a year for the males or
vice a versa

I would be weary of any vet neutering a kitten under 4 months almost sounds
like something a kitten mill would do

Uhhh....when did Rolodex come out with  a line of cats?

I agree with most of the comments stated in this thread.
Abridged, limited information about spays and neuters follows;
It is a commonly accepted practice in the USA to spay or neuter any cat
(pure or mixed) that is not going to be used for breeding purposes.
Female cats that are spayed before their first heat have a significantly
lower incidence of developing mammary tumors (which are usually malignant in
cats).  6 months old is a widely accepted age to have a normal, healthy cat
spayed.  Spaying a cat during heat or pregnancy will have an increased risk
of complications but is not an uncommon undertaking.  Individual Vets'
recommendation or insistence upon an overnight stay after abdominal surgery
may depend on the owner's ability to provide post-operative care at home.
Male cats need to weigh at least 3 pounds before neutering (usually around 6
months of age).  Statistics and owner reports show that neutering a male cat
at any age will decrease the incidence of urine marking, roaming, fighting
and other secondary male characteristics in up to 90% of male cats.
Neutering a male is a less invasive surgery than a spaying; since a spay is
abdominal surgery and neutering (a male with 2 descended testicles) does not
usually require abdominal surgery -- unless there is a retained testicle,
and therefore, males can usually go home the same day as their surgery,
although they will still require special care at home.
Be sure that your Vet educates you on the risks and complications of any
procedure or medication before its undertaking.  Generally, younger, healthy
animals will have a lower incidence of complications.   Vets may require,
advise or only suggest bloodwork before surgery to aid in safe anesthesia.
Your Vet may advise that bloodwork is not necessary due to your pet's age
and health status.  Personally, I would require recent bloodwork for any
geriatric (8 years old or older) and/or non-healthy animal (of any age).  I
would strongly advise recent bloodwork for a middle-aged (4-7 years old)
animal  as it can assist in diagnosing non-evident health problems.  In
young, healthy animals I would inform the owners of the benefits gained and
state my own personal preference for having recent bloodwork, but leave the
final decision up to the owner.  I would never deny any owner the benefit of
a work-up if requested, even if I personally did not feel it necessary.
