Many, many years ago.
As a kitten, Firstcat sometimes got up in the middle of the night to play. One night, my mum had left in the dining room a nearly finished sweater she was knitting together with the last full ball of wool.
She went in the next morning to find that overnight, Firstcat had got in there somehow, been playing with the remaining ball of wool - and had unwound the flipping lot of it by batting it around the room. So there we were, faced by this giant Cat's Cradle - I mean it was horror movie stuff.
Under the firstchair, over the table, under the carving chair, over the carving chair, under the carving chair again, around the sideboard mirror spindle (three times), over the table.............It just went on and on.
And because he was my cat, and because it was the last ball of wool for that sweater, I had to very gently unwind and very gently re-roll every last blessed inch of it.
Took me - hours it must have been !
