Roadkill ones don't count mind 
It's like the 'ever seen a baby pigeon?' question. We know they exist but whose ever seen one?
I walk through the park every morning and I'm surrounded by squirrels jumping about and climbing trees, there's tonnes of 'em, however despite the masses, I have yet to chance upon one toe up in the grass dead as a doornail.
Where do squirrels go to die?
Perhaps maybe....they don't die!?!?!? Squirrels could be the fountain of youth!
I'm thinking an experiment in squirrel blood drinking is in order!
