Animal uthenization is cruelty to a lot of people. I myself included. Animals should have equal rights as humans do. Many of the human population treat their pets as their own children, just with more hair, a bark or meow, or even a moo, because they care for their property. I believe if animals have food, water, and shelter should be left alone to be cared for by their owners and the SPCA or other animal shelters should not interfere.
