Both are in HD, but the YouTube one is at 1080. There are no differences other than that, so enjoy your preferred flavour.
The idea for this video was inspired when a commenter on one of Rattus's cooking videos claimed that rats are disease-ridden animals. I wanted to rebut that hoary old chestnut by illustrating at least one rat's grooming routine.
Grateful thanks go out to Pistolpup for his camera work and loaning the use of his home for the video shoot.
