Sterilization (Spay & Neuter)

Pet Overpopulation: The Simple Solution. Education, Legislation, Sterilization!


© 2003 Laurie Goldstein www.StrayPetAdvocacy.org

According to The Humane Society of the United States, six to eight million cats and dogs enter shelters in the United States each year.  Three to four million of these animals are adopted out. That means three to four million animals are murdered each year.  Many use the word "euthanized," but we prefer to call it what it is. These animals committed no crime; most of them never harmed a human. They were born, plain and simple.

And animals are great at reproducing.  When researching the subject of pet overpopulation, you will frequently find the statements that "over the course of six years, one female dog and her offspring can theoretically produce 67,000 dogs," and that "over the course of seven years, one female cat and her offspring can theoretically produce 420,000 cats."  While these numbers are a mathematical exercise, not a biological reality, they are used to make a point. (Actual studies taking into account average birth rates, survival rates and life expectancy of feral cats indicate that "Realistically, over 12 years, one unspayed female, with all her unspayed female offspring, reasonably can be expected to be responsible for over 3200 kittens if there is no human intervention." [Ref 1] )  But the bottom line is the same.  There are a lot of homeless animals out there, and without human intervention they are multiplying. 

There aren't enough homes for them all.

Our time-honored tradition and system of calling "Animal Control" to catch or trap stray or feral cats and dogs, take them to crowded shelters, then kill the "surplus" animals to make room for the new ones has proven inefficient and expensive. This method of pet overpopulation management costs the U.S. taxpayer close to $250 million in euthanization and carcass disposal alone. The bulk of this financial burden fell on the municipalities and counties of our country.

In a shelter, we must pay for the cost of the shelter, its maintenance and upkeep, the animals' food and healthcare, the cost of running adoption programs - and when these fail to place all the animals in homes, we then have to pay to murder the "surplus" cats and dogs.  There is a far simpler solution.  Stop the problem at the source.  Sterilize the animals.  Prevent unwanted, unplanned, unexpected births.  The benefits?

  • It's Healthy. Sterilization has proven to improve the quality of life, health, and behavior of our pets. 

  • It's Humane. Free or low-cost sterilization programs have proven to be effective - VERY effective, in fact.  According to a study conducted by Animal People, "Who Needs Low-Cost Spay/Neutering?" (link included in resources, below) these programs reduce the number of animals that had to be euthanized annually by 30-60% (even in those towns and cities where human populations have been steadily increasing). 

  • It's Cost-Effective.   Free or low-cost sterilization programs have proven to be cost-effective, reducing the cost of animal control. Lower stray pet/feral animal admission PLUS a lower euthanization rate equals tax dollar savings.  Communities implementing free or low-cost spay/neuter programs have seen savings of over $3.00 for each $1.00 spent on the program ("The Need for Low-Cost Spay/Neuter Programs!" ©2003 www.StrayPetAdvocacy.org).

If your community doesn't care about killing its surplus animals, it should certainly care about the size of the taxpayer burden spent for animal control. If you can't appeal to their hearts, appeal to their purse-strings.

As The Humane Society of the United States puts it, "The solution can be simply stated.  Its implementation, however, requires sweeping efforts from a variety of organizations and people, including you."  (www.hsus.org)  Here we provide presentations, resources, and research to support and aid anyone who wishes to change the local legislation and put in place programs to manage the "pet overpopulation" problem.

 Education.  Legislation. Sterilization. Step one is right here and it starts with you.

Karen Johnson, National Pet Alliance.  "A Report on Trap/Alter/Release Programs."  Excerpt: "After a six-year study and daily observation of a feral cat colony, it has been documented that stray female cats start cycling when they are 4-6.9 months old [Ref2], or as soon as the days are long enough. January and February are the start of the kitten season, with the litters born in March and April. These cats have an average of 2.1 litters per year of 4.25 kittens [Ref3]. 42% of the kittens will die by the age of two months of natural causes [Ref4]. Many more will end up at the shelter. Those who escape early death and the shelter go on to be prolific bearers of kittens over their short lifespan of approximately three years [Ref5].

"Taking the mortality into account, along with birth and death rates, the average stray female will have 5.25 litters in her lifetime, encompassing 22.3 kittens. At age two months there should be 12.9 survivors, roughly six females and seven males (at maturity, roughly 2/3 of the stray cat population is male [Ref6], due to the high mortality of females during first pregnancy and birth), which will decrease to four females over time. These six females will go on to have their 22 surviving kittens each. Realistically, over 12 years, one unspayed female, with all her unspayed female offspring, reasonably can be expected to be responsible for over 3200 kittens if there is no human intervention."

"Who Needs Low-Cost Neutering?" ©1994 by Animal People News, June 1994.  "Low-cost neutering doubles the number of poor people who get their pets fixed and cuts animal shelter intakes in half," begins this article by Animal People News.

"Any doubts about the efficacy of low-cost neutering should be laid to rest by the results of a new national study carried out over the past six months by ANIMAL PEOPLE, under sponsorship of the North Shore Animal League. Perceiving lack of hard data on the efficacy of low-cost neutering and consequent veterinary resistance as the two main obstacles to the availability of low-cost programs, NSAL president John Stevenson commissioned the ANIMAL PEOPLE study in December 1993, on behalf of Spay USA, a project of NSAL."  If you have trouble with this link, please copy and paste this web address into your browser: http://www.animalpeoplenews.org/Low-costNeut.html

Model Statewide Spay/Neuter Programs

 

New Hampshire


New Hampshire decided in 1993 that something had to be done to stop the killing in the state's animal shelters, as well as saving the taxpayers money.  New Hampshire's two main programs are a Low Income Assistance program, in which a qualified person is charged $10 for the spay/neuter and up to $35 in pre-surgery immunizations, and a "break" for spay/neuter surgeries for animals adopted from shelters.  New Hampshire has the lowest euthanasia rate in shelters in all 50 US states, and this is credited to the success of this program.

New Jersey


New Jersey was the first to implement a state-wide pet population control program.  Started in 1984, it was originally funded solely by a $3 surcharge on non-neutered dogs, and the $10 or $20 co-payment fee by the animal owner for the spay/neuter. In 1994, New Jersey added a Pet Friendly License Plate that generated over $1 million toward the program from 1994-1997.
