A friend bought a (domesticated) pet rabbit. You know, like, a house-trained kind - the sort that poops in a litterbox (like a cat) and that can be snuggled with in front of a TV in the evening. A cute thing!
That same friend also learned that, apparently, even domesticated pet rabbits chew through internet cables if given a chance. Even if those internet cables are nailed into bottom of skirting-boards :)
