I think he's saying that vacuuming is one of the least grueling chores he ever gets, so his day isn't too bad despite the shearing.Is it okay if I don't get the 'vacuuming' thing? Did he vacuum his fur out? Because that would hurt. D:
I don't think we've ever seen him with morning fur before. It seems the fur that was under his pajamas looks no more or less ruffled.
As for "grey fox," I take it in the literal sense: a fox who is colored grey, regardless of exact species.
