I had a cat once that used to bring cucumbers home! There must have been a very annoyed gardener nearby, growing these things and seeing them go missing. Apart from the one still in shrink-wrap. She'd drag them in through the cat flap and call her kittens, whom would arrive and look very confused.
She was half ferral, we were looking after her for Cat's Protection, which might have been a reason for her weird tastes in food..
