A fire caused extensive damage to a Richardson pet store Saturday morning, killing dozens of animals trapped inside.

Employees at the Serpentarium, a pet store specializing in reptiles, arrived to open the store on August 12 and noticed the building was filled with smoke. When the Richardson Fire Department responded to the scene, fire crews noted heavy smoke emanating from the building.

Firefighters quickly put out the blaze, and no humans were injured in the incident. However, a large section of the store and multiple animal habitats were destroyed.

About 50 animals were killed in the fire, as well as about 90% of the rodents being kept as food supply for the reptiles.

However, some animals survived. The Richardson Fire Department posted an image of Recruit Brady Faulkner holding a bearded dragon he rescued from the fire.

The Serpentarium posted a video showing store personnel searching the animal habitats for any surviving reptiles and amphibians, including pythons, frogs, geckos, sand boas, and turtles. The video also showed some dead animals being removed from their burned enclosures.

Approximately 30 surviving animals were placed with community volunteers who offered to foster them. The Serpantarium announced on August 15 that all surviving animals are now in foster homes.

One volunteer, 16-year-old Felix Keith, showed up at the store hoping to take home a leopard gecko to foster.

“I brought just a little tank, just some[where to] hide so it can feel secure,” said Keith, according to Fox 4 KDFW. “Obviously, I didn’t want to hold it in the car. I wanted it to feel safe.”

In a Facebook post, the store expressed appreciation for the community’s help.

“We greatly appreciate the tremendous support you all have shown. We are forever grateful,” the statement said.

The fire department is still investigating the cause of the fire, but it is believed that it was electrical, WFAA reported.

Robert Coral, the owner of the Serpentarium, told Fox 4 that the fire could have been started by one of the facility’s heating appliances.

“There’s a lot of heat lamps here, 50 +. But it could have been a heat lamp, could have been a heat pad, it could have been a timer, digital timer on the side, it could have been the wiring itself,” said Coral.

The store remains closed for now, but Coral plans to reopen for business in a next-door unit before the end of the month.
