Last night I was lucky enough to film this busy beaver as it was grooming its fur at the edge of the river.

Beavers have to groom several times a day to spread oil through their fur to stay waterproof. Beavers will sit on their tails to access oils through their cloacas. In addition, anal glands secrete oil through skin pores to hair roots. From there it is distributed with the front feet, teeth and grooming claws over the whole body to keep the fur sleek, oily, and water-repellent. They groom each other to work oils around in the hard to reach areas.
