A very cute gray-and-white kitten was apparently stolen from the New York Avenue Adoption Center this weekend, according to the Washington Humane Society.

Callista, an approximately eight-week-old kitten, disappeared from the center during an adoption event Sunday afternoon. The Washington Post has more:

[Scott Giacoppo, the group’s vice president for external affairs,] said the room where prospective owners are allowed to play with the cats is closed, and it is inside another closed room — meaning it is unlikely Callista escaped on her own. He said staffers had “searched the building high and low,” making sure the kitten was not placed in the wrong cage after the event, and found no signs of her.

“If she did escape, she would have gone right out into our parking lot. Someone would have seen her,” Giacoppo said.

The Washington Humane Society is reviewing security footage, according to a message posted on its Facebook page. The group is offering a $1,000 reward for Callista’s return.
