An animal advocacy organization says Michigan has joined Delaware in a "no kill" designation for shelters.Michigan has reached a threshold where 90 percent of cats and dogs are being saved on average throughout the state, according to the nonprofit Michigan Pet Fund Alliance."This is an amazing first for our state,” said Deborah Schutt, the alliance's founder and chairwoman.Around a decade ago, more than 120,000 cats and dogs died in shelters there, but that number has since been reduced to about 13,000 last year, the group said."While it’s exciting to see Michigan as a state achieve No Kill status by reaching the 90% goal, we still have a few communities struggling to save lives, especially with cats," Schutt said. "We will continue to work with shelters and rescue organizations to implement best practices, decrease overall length of stay in the shelter and improve the quality of life for homeless pets while they are in shelter," she said.Related video: What it's like to drive 300 miles to save animals from a shelter.
