Tomorrow's lunch will consist of this evening's left overs, which I tipped in to a tupperware box. As it was still warm I left it on the kitchen bench with the lid off with the intention of putting it in the fridge once it had cooled.
The cats had been suspiciously quiet when I heard the tell-tale 'thud' on the kitchen floor. Sure enough, one of them had dragged several pieces of beef out of the box on to the kitchen bench. 
Short of getting a very yummy and extremely calorific sarnie from M&S tomorrow I have nowt else for lunch. So would IBU to just wipe the top layer of beef on my jumper and eat it anyway?
