The Problem

More than 70,000 puppies and kittens are born each day in the United States, compared to 10,000 people. That means that even if every man, woman and child in the country were to adopt an animal, there would still be an enormous surplus of animals.

The estimated number of unwanted animal in the country exceeds 7.5 million. Many of these animals lead lives of misery, privation, disease and neglect. Others are spared this torture only by being euthanized in animal shelters throughout the country.

The Solution

The easiest and most effective way to reduce the number of unwanted animals  is to make sure that family pets do not produce unwanted offspring. San Francisco Animal Care & Control and other Bay Area animal welfare organizations are committed to this goal. Spay/neuter surgery is an effective way to curb animal abandonment and has additional benefits for the health and behavior of your pet.

Benefits of Spay/Neuter

  • Reduces the risk of reproductive-related cancers and infections in both males and females
  • Decreases desire to roam resulting in less incidences of injuries such as animal bites or auto accidents
  • Reduces the number of unwanted animals that end up in shelters
  • Reduces spraying and marking behavior
  • Decreases aggressive behavior
  • Creates a safer community, with fewer potentially dangerous animals

What does it mean to spay and neuter?
Why do you spay/neuter puppies and kittens? Doesn't it harm them to do this when they are young?
Will my pet become fat or lazy because of this operation?
Should I expect to see a dramatic change in behavior after the surgery?
It seems to me preventing pets from having litters is unnatural. What do you think?
Does neutering male cats cause urethral obstructions?
It seems silly to have a male neutered when they aren't the ones having the litters. Why not just spay the females?
I’ve heard it’s better to allow your female to have one litter before she is spayed. Is that true?
I’m afraid that the operation will be too costly. Are there low-cost spaying and neutering alternatives for concerned pet owners?
