SAN ANTONIO — Officials with Animal Care Services are joining the spirit of Black Friday with an adopt-a-thon aimed at finding forever homes for the shelter’s “harder-to-place pets.”

The Friday event is the culmination of a weeklong effort to spur adoptions heading into the holiday season.

“Over the course of the last couple years, Animal Care Services has really tried to essentially change our approach to the sheltering business,” ACS spokeswoman Lisa Norwood said. “One of the things we saw with successful shelters throughout the country is you almost have to approach the sheltering business with a retail perspective. Look at it like a business.”

For families who are considering adding a pet to the family, ACS officials recommend checking out the animals sheltered at its Adoption Center at 4710 Texas 151.

Bethany Heins, ACS’s live-release manager, said the adopt-a-thon is an effort to compete with retail options.

“Our dogs and cats in-house are just as good as the ones you buy from a pet shop or in the newspaper or off of Craigslist,” she said. “We want to hit that retail market and showcase our animals.”

The Black Friday event, which includes reduced costs and two free tickets to SeaWorld with each adoption, will focus on dogs and cats that are black. They’re typically harder to place, Norwood said.

But ACS officials will “loosely” interpret the deal. If there’s a black mark — even a freckle — on the dog or cat, the reduced adoption prices will apply on Friday.

The event will run from 11 a.m. to 7 p.m. at the Adoption Center. Adoption fees for dogs and puppies will be $50 and cats and kittens will be $15.

All the animals at ACS have been sterilized and vaccinated — usually additional costs after animals are bought from breeders, officials said.

They also note that when families adopt shelter animals, they’re saving lives.
