Spay and neuter are descriptions of sexual sterilization
surgeries for pets. The clinical terminology is ovariohysterectomy in females
and castration in males. The
surgeries require general anesthesia and are recommended for every pet for
multiple reasons.
The behavior of pets changes as they reach puberty (about
six to nine months for dogs and cats). Males become more aggressive, start
marking territories with urine (both indoors and out) and begin displaying a
tendency to escape and roam. When they smell a female in heat (even a mile
away), almost nothing will stand in their way. They will jump fences or
balconies, cross water and highways, and may wander far away.
Females also have roaming urges and may become more
aggressive. Female dogs have heat cycles twice a year whereas cats may cycle
every two weeks. Dogs may bleed for four to eight weeks, creating quite a messy
situation in the house. You might also find a group of male dogs, not
necessarily nice, parked in front of the house waiting for the opportunity to
get to your female in heat. Cats will vocalize loudly all hours of the day and
will roll and rub continuously, enough to wake up even the soundest sleepers.
They also attract intact males, who will perform free all night serenades under
your window.
It is very difficult to keep animals in heat protected and
it does not take much to end up with a litter of puppies or kittens. A leash or
fenced-in yard is no match for the call of nature. It is not hard to understand
that any unwanted pregnancy contributes to pet over- population: ten pregnancies
easily produce fifty to eighty newborns.
Spayed and neutered pets have a lower risk of some serious
health problems. Early spay of females reduces occurrence of breast cancer
significantly. They also do not get deadly pyometras (uterine infections) and
have less incidence of diabetes.
Neutered males have a lower incidence of prostatitis
(inflammation of the prostate), they are less aggressive and do not run away as
often and risk getting lost or becoming an accident victim.
If your pet is not neutered or spayed, please take the
opportunity to have the surgery done by your veterinarian.
