It's Monday, so let's start out with something wonderful and goofy — like this video of a squirrel and cat enjoying a rooftop romp. The story behind this video is that the squirrel was raised by the woman who owns the orange tabby. The squirrel grew up to be friends with the cat and, though it was returned to the wild, the playful creature still stops by every so often to check in with its old buddy. Watching the squirrel egg on its older "sibling" and literally roll all over this patiently tolerant friend is sure to put a smile on your face.
