My Wife's mother went down under last week to visit her son (my brother-in-law).  We received this video today, which I first viewed at the Doctor's office with my daughter, who has an ear infection.

The email that I originally received with the video link said that the animal in video was a kangaroo, but the video title says Wallaby.

What's the difference between a Wallaby and a kangaroo and which do you think this is in the video?

BTW - if you saw the video here titled "Where The Hell Are My People?" with Colby the Yellow Lab Basset, the answer is that his people are currently in Australia and one of them is apparently in the video above petting marsupials of unknown make and model.
