Brigit belongs to New Zealand resident Sarah Nathan, who recently documented the cat's bizarre behavior on her Facebook page, posting a photo of Brigit with many of the underwear and socks she has retrieved.
"Now it's getting silly... Every morning we wake up to more," she wrote. "I've put notes in every letterbox in the street. Someone must be missing this stuff."
Nathan has an idea of where the items are coming from, though. In a BBC interview, she mentioned that the undergarments were probably from a nearby apartment "full of blokes."
