Hank the cat looks up from its cage at the Salt Lake County Animal Shelter on Thursday as it waits to be adopted. Some animal advocates are asking the West Valley-Taylorsville Animal Shelter to cease use of the gas chamber and set a goal of becoming a no-kill facility. They point to the Salt Lake County Animal Shelter as an example. That shelter offers discount adoptions, works with rescue groups and has longer animal holding times.
