There’s a new development in the ongoing controversy over how Michigan's animal shelters euthanize unwanted dogs and cats.

As we showed you two years ago, Berrien, Cass, Van Buren, and Branch counties use a gas chamber. 

Opponents say that's not humane. And now the Michigan Senate agrees. It unanimously passed a bill banning chamber use in favor of lethal injections.

This issue now moves to the house.
