I actually got my anwser by doing a search of other posts ....
I just took him to the vet last Wednesday and she gave him a pill for deworming, so I'm guessing that's been dealt with ... I'm left to assume that he just has some poop still stuck to his fur .... b/c he doesn't do it all the time.
Anyways, I guess I'll just keep an eye on him for a while.
I have seen this procedure done. it is said to be just like popping a zit. the anal glands being cleaned and expressed are the same thing. they are having the "waste" caught inside removed - like dust and hair in a vaccume cleaner... but yea get those anal glands checked out asap, or they can get infected...
