Some surprising facts: 

In seven years, one female cat and her offspring can produce 420,000 kittens.

In six years, one female dog and her offspring can produce 67,000 puppies. 

For every person born, 15 dogs and 45 cats are born.  Every day in the United States, thousands upon thousands of puppies and kittens are born because of the uncontrolled breeding of pets.  Add to this the offspring of stray and abandoned companion animals, and the number, as evidenced by shelter euthanasia rates, is overwhelming and heart wrenching.

Each year, U.S. shelters take in 6-8 million dogs and cats; of those 3-4 million are adopted and 3-4 million are euthanized.

Only 1 in 9 cats and dogs born in the U.S. will find a home.
