Who dunnit?

Well - if we are talking about the jigsaw, although Martin did the edges at the start, I did all the rest. But if we are talking about who turned the 1000 piece jigsaw into a 999 piece one, the main suspects are feline. Although all four of our/ visiting cats have been seen in the vicinity and even on top of it as it was being done, the smart money is on our Mittens and Katie’s Nico being accomplices. Will we ever know? Will we ever find the piece???
