Animal Population Control: Introduction and Index


Estimates vary, but somewhere between 10 and 20 million unwanted dogs and cats are euthanized every year in the United States alone. Several million additional animals starve to death, are shot, killed on highways or meet some other unsavory end during that time.

Almost everyone recognizes this as a tragic situation, but fewer have an appreciation for the many other consequences of pet overpopulation. Animal control programs are very costly to society, stray dogs inflict dozens of serious bites on human children each year and unowned animals contribute significantly to sanitation problems in large cities.

The focus of this section is on the causes of and potential remedies for excessive numbers of dogs and cats. It should be recognized, however, that problems of overpopulation exist for other animals as well, including certain situations involving wild horses and deer. Of course, there can be no doubt that the most serious and threatening problem of overpopulation is that of mankind.

Core concepts for animal population control are presented as the following topics:
