The other day, I had some comments about North Carolina's high rate of euthanization of unwanted pet animals at county operated animal shelters—almost twice the national average! I dwelt on the lack of funding for space adequate to keep the animals longer to better their chances of being adopted.
Among the e-mails I got in response, a number of viewers said the bigger problem is the lack of responsibility of some owners who allow their female dogs and cats—especially cats—to roam outside, and they, as Nature directs, get pregnant as often as possible, producing unwanted litters that are dumped at the shelter as soon as they are weaned. Those viewers are right. (But you can only cram so many thoughts in a minute and twenty seconds, and that's the reason for this follow-up.)
