Speedy has stolen so much loot that its owner had to post leaflets throughout a northern Swiss town saying "Help, our cat steals!" and inviting people to recover their missing things.
Margrit Geiger of Wiesendangen said her kleptomaniac cat switched three years ago from bringing home mice to stealing badminton shuttlecocks, all to impress her teenage son.
Then the cat began specializing in gloves, scarves and T-shirts. The latest obsession: underwear and black socks.
Geiger told the Swiss daily Blick the cat has nabbed more than 100 items, and the paper said Thursday some neighbors have already claimed items back.
Veterinarian Brigitte Buetikofer says animals steal to gain attention, so ignoring them is the best cure.
