Apparently even fake - red squirrels are reaching extinction, sometimes you just have to settle for a grey squirrel over no squirrel at all.
I saw a red one in the window display of Collard Manson, Sheffield http://www.collardmanson.com and it outshone all their glorious jewellery, so I hunted down this similar model (originally made by Hobbycraft) and I think you'll agree it looks ridiculous. And really lovely.
