Arrrggghhhh my potatoes!

Came home from work to find 2 of my potato containers have completely flopped over. Can't see any signs of blight, no marks on the stems and foliage still all looks healthy. Apparently my 3 year told hid daddy it was the cat, which usually means he's done something. Then we found out that they'd been to the allotment at nursery and had been planting potatoes. Do you think it was something he's done or blight or something else? They're well watered, bring green, stems are mainly in tact just floppy but still feel pretty firm. Sorry I haven't got any pics my phone battery is flat.
