The woman allegedly pilfered the cat from a fellow shopper at the nearby discount superstore, where another woman, for her own inscrutable reasons, had left a kennel full of kittens on the ground.
When she returned to the kennel, a kitten was missing.
"Somebody would have had to go open the cage and take it out," Cpl. Holly Largy of Langely RCMP told reporters.
Police have since identified a "person of interest" in the kitten theft case. No arrests have been made.
Stealing a cat falls under Section 334 of Canada's Criminal Code, which deems most animals as property with a value of less than $5,000. Penalties range from a fine to jail time, although jail time is rare.
Police are asking anyone with information about the woman seen in the picture to contact Langley RCMP through the website or by calling 604-532-3200.
