Okay, this is so cute it isn't even fair.
According to The Telegraph:
This baby squirrel suffered injuries to her leg and was separated from her mother when she fell from a tree - and she is not even three weeks old. The grey squirrel, called Violet, endured the ordeal when the branch her nest (known as a drey) was laying on was cut down. Fortunately, the couple cutting down the tree spotted Violet and immediately phoned the Wildlife Aid Foundation for advice on what to do.
