San Antonio's Animal Care Services Department has achieved no kill status for the city.
That means at least 90 percent of the shelter’s healthy, adoptable animals were placed last month.
City leaders say that makes San Antonio the largest city in the nation to achieve no kill.
Officials say they're happy to celebrate all of the hard work done by staff and volunteers, but they know there's still much to do.
"It'll probably never reach 100 because of the sick and injured pets that come in. What we need to remember is every day, we're still bringing pets in. This is not a destination, it's a journey. Every day, pets come in, and every day we need to find great homes," said Kathy Davis Director of the San Antonio Animal Care Services.
Animal advocates credit outreach and education efforts.
"We have a lot of people that come to the shelter, that want to adopt. That outreach to show adoptable puppies and dogs and even cats is great. It gets out in the community that we have some great animals that are just waiting for homes. Some have waited a few weeks, for that right family to come along,” said Clare Joscelyne of San Antonio Pets Alive.
During the last fiscal year, ACS and its partners rescued or placed nearly 20,000 animals.
