Spay, spay, spay. An unspayed mother cat can have 12 kittens the first year. The next year, she and her offspring will increase the cat population by 67. By the fifth year, there will be 11,801. And by the ninth year there will be 11,606,077 of them - all from that very first unspayed cat.
Over 11 million animals are placed in shelters each year. Half get adopted.
