VALLEJO (CBS13) – A 19-year-old in Vallejo is looking for a roommate, but compatibility may be an issue. She’s an Orca. A Killer Whale at Six Flags Discovery Kingdom. And a Vallejo woman is complaining that the park is breaking the law by not providing a companion.

Killer whales in captivity need companionship.

“It’s the law,” explained animal activists Wendy Brunot. “It’s been almost six months that Shouka has been alone.”

Brunot has started an online petition demanding Six Flags find Shouka, a 19-year-old female Orca, a pool mate.

So far, Brunto has collected 700 signatures. She says Shouka’s current circumstances are cruel and inhumane.

“The Animal Welfare Act requires that marine animals when ever they’re primarily social in the wild that they are housed with at least one compatible companion,” Brunot said.

In a written statement, Six Flags responded, “Due to recent compatibility issues, Shouka and her companion for the last seven years, a male Atlantic bottlenose dolphin, have been separated.”

Six Flags did not say why they were separated or if the move was permanent. But park officials say they are actively searching for a suitable companion for Shouka.

“The best thing for her, in my opinion, would be to be sent back to her family in France where she came from if they cannot find a companion for her,” Brunot said.
