Re "A new approach aims at an old pet problem" (Page A6, Dec. 3): An injection that can neuter animals is an exciting prospect for pet owners, shelter workers and veterinarians alike. For those of us whose hearts break when we visit the local animal shelter, this is a great solution to a tricky problem. Many animals still aren't sterilized and they are filling the shelters with puppies and kittens in need of homes. Unfortunately, older dogs and cats in the shelter also need homes, these adorable babies often get first priority. Another unfortunate fact: Many of those babies will wind up back in the shelter when their cuteness wears off and realities of pet owner responsibilities set in. Only time will tell how safe and effective this injection method using the drug Zeuterin is, but if it can lessen the number of animals in shelters, it's worth a try.
