Here are a few benefits to spaying and neutering your pet:
Your female pet will live a longer, healthier life. Spaying helps prevent uterine
infections, such as pyometra, and breast cancer, which is fatal in about 50 percent
of dogs and 90 percent of cats. Spaying your pet before her first heat offers the
best protection from these diseases.
Neutering provides major health benefits for your male. Besides preventing
unwanted litters, neutering your male companion prevents testicular cancer, if done
before six months of age.
Your spayed female won't go into heat. While cycles can vary, female felines
usually go into heat four to five days every three weeks during breeding season. In
an effort to advertise for mates, they'll yowl and urinate more frequently-sometimes
all over the house!
Your male dog won't want to roam away from home. An intact male will do just
about anything to find a mate! That includes digging his way under the fence and
making like Houdini to escape from the house. And once he's free to roam, he risks
injury in traffic and fights with other males.
Your neutered male will be much better behaved. Neutered cats and dogs
focus their attention on their human families. On the other hand, unneutered dogs
and cats may mark their territory by spraying strong-smelling urine all over the
house. Many aggression problems can be avoided by early neutering.
Spaying or neutering will NOT make your pet fat. Don’t use that old excuse!
Lack of exercise and overfeeding will cause your pet to pack on the extra pounds-
not neutering. Your pet will remain fit and trim as long as you continue to provide
exercise and monitor food intake.
It is highly cost-effective. The cost of your pet's spay/neuter surgery is a lot less
than the cost of having and caring for a litter. It also beats the cost of treatment
when your unneutered tom escapes and gets into fights with the neighborhood
Spaying and neutering your pet is good for the community. Stray animals
pose a real problem in many parts of the country. They can prey on wildlife, cause
car accidents, damage the local fauna and frighten children. Spaying and neutering
packs a powerful punch in reducing the number of animals on the streets.
Spaying and neutering helps fight pet overpopulation. Every year, millions of
cats and dogs of all ages and breeds are euthanized or suffer as strays. These
high numbers are the result of unplanned litters that could have been prevented by
spaying or neutering.
