These cutesy wootsy US imports carry a virus to which they are immune but which has decimated the native red squirrel. They also cause a great deal of carnage among nesting birds by eating their eggs and young, plus as had been said, you wouldn't want them in your loft chomping their way through electrical circuits. Hard to really see an up side to them being introduced into the UK, so maybe the answer is to create a market amongst the trendy Hoxston Hipsters lot for free range squirrel burgers? If only they could get Nigella Lawson to front it!:P
