A Winnipeg pet shelter got a rare surprise when a feral cat gave birth to her kittens in the rescue.

Winnipeg, meet Unicorn Andy, an eight-week-old kitten who is also a male calico – something that happens for maybe one calico cat in 10,000, said D’Arcy Johnson, CEO of D’arcy’s ARC.

“In all these years of working at the shelter and all my years of working in the clinic … I haven’t seen one, and even some of our long-term veterinarians have never seen them,” he said.
