I've been waiting for a long time to do this. You see, because Darwin has thick fur and is unable to groom his back, he had a series of dreadlock like mats on his back.
I was perfectly willing to groom him with a brush but he would take numerous swings at me (claws out) or attempt to bite both me and said brush.
So today at feeding time I took the radical step of giving him a hair cut. While he was occupied with tuna, I took a scissors and cut all of the unsightly clumps off.
Now he has this nice bald strip down his back but no more dreadlocks....
