You're probably thinking that squirrels don't drink coffee. Well that's easy to assume as you've probably never seen them drink coffee. This is however because they do not have any cups left in the cupboard. Carrying a mug whilst leaping through the trees is a tricky affair, hence there's quite a few breakages.
Help the squirrels in your garden get the caffeine they deserve and buy them one of these Squirrel Coffee Cups. Or just buy this as a bizarre or novelty gift for someone that has everything, they won't have one of these....
