Midnight, a glossy black female cat, yearns for affection. She represents scores of cats and kittens who end up at the Salt Lake County Animal Shelter each week during the spring, most of whom are euthanized because there aren't enough homes for all. This senseless slaughter could be prevented if only pet owners would spay or neuter their pets. If you would like to adopt Midnight or another cuddly ball of fur, visit the shelter, 511 W. 3900 South. Neutered cats cost $15. The sterilization fee is included when unsterilized cats are adopted: the total fee for males is $25 and for females is $40.
