Here's a link to a website that has info about the anal sacs (glands) and how to squeeze them - I'm still just not ready to do this to the kitty myself. I guess I don't want him to hate me like he hates the vet.

My kitty has never done the "scooting" they describe, but he does secrete a nasty-smelling liquid. It sounds like your Nutmeg has the same problem. Good luck - let me know if you get bold enough to do the squeezing!
