Now here's something your cat would really appreciate.
But what's IN the yarn is what its human master would appreciate! Wonder if it's Kirby plush toys? It wouldn't make sense if it wasn't. Only in Australia.
...And what if there's nothing in the ball of yarn? Well, like I said, it makes a good cat distraction for a couple hours, or if you somehow enjoy knitting as much as you enjoy gaming (ooh).
