It is actually Ada, sweet little, stealth-ninja, Ada.
My mum decided that turning the container upside down would stop her from getting into the biscuits - it just ended up with Ada pushing the container around the kitchen floor with her nose until it fell over on its side and she could finally re-open it and scoop out some biscuits.
Then the big, bad human put the container away in the cupboard.
Babbage has been re-arranging my mum's makeup brushes today ( on to the floor ) and paddling in the toilet. I always put the lid down, as no one wants a cat jumping up on you for cuddles then later finding out exactly why its feet were wet, but my mum is not yet fully bengal trained. Her cat, Basil is shamefully well behaved.
