So the hubby noticed yesterday that Chaos has been scooting a time or two on his bottom. I'm new with all this anal glad stuff. Does this mean I need to take him in to have them expressed? He is suppose to go back Monday for a recheck on his ear infection, so is it ok to wait til then or should I go ahead and take him? Also, is there a way to tell if they are full other than when they do the "butt scootin boogie"?
