An AirTag placed around the neck of a cat who had recently given birth led Good Samaritans in B.C. to the secluded spot where she had been raising a littler of kittens.

But it was the patience and perseverance of two rescuers with the Regional Animal Protection Society that led to a happy ending for the feline family.

Last month, Ken Friesen and his wife Lisa—described as the organization’s master trappers—got a call about a lactating cat found roaming a Surrey street who had been scooped up by concerned residents and outfitted with the location tracker.

“They could be anywhere from two days to two months old,” Ken told CTV news, referring to the kittens. “We had no clue, and it was really essential that we find these babies.”
