I just got back from the Vet today in fact, getting Vegas's anal glands expressed. He did not do a spin, but more like rubbing his butt on my area rug kind of like a scoot. He needs more than a squeeze the last two times he has had it done, he has to have an internal expression. It kind of sounds like what Barney was doing. My Vet only charges $5.00 for internal expressions.
