Animal Care and Protective Services may have to start euthanizing animals soon because of overcrowding.
It's urging residents to consider adopting one of the hundreds of animals in their shelter.
The shelter can only hold about 390 animals, but as of Thursday it had 466 after an unexpected number of animals have recently been turned in to the facility.
"We saw the news that they have way too many animals here and they're needing help, and we're animal lovers and we're starting our family, so we're kind of looking for a dog," said Melanie Solis, who's looking to adopt.
"I'm asking all those young kids out there who want a dog or a kitten, cat, please reach out to us. It's so important," said Mayor Alvin Brown, who made a stop at the shelter Thursday.
Scott Trebatoski, director of ACPS, said the number of animals at the shelter must go down immediately to keep them from being euthanized. No animals were put down Thursday because of overcrowding.
"It's very heartbreaking," he said. "We love them all when they're here. We get to see their personalities. We don't ever want to see an adoptable animal be euthanized."
As of Thursday afternoon, eight animals were fostered, 30 were adopted or returned to their owner, and 65 were rescued and taken to a pet placement partner. There will be 30 pets ready for adoption Friday.
People were still trying to adopt pets even after hours Thursday.
Anyone who wants to adopt or foster can go directly to the shelter at 2020 Forest Street, just west of downtown Jacksonville, from 10 a.m. to 4 p.m. Tuesday through Saturday.
Adoptions are being offered for $30 each, or two animals for $40, which includes the license fee. Dogs and cats older than 3 are free.
