If it's anal glands....it wont smell like feet. It's more than likely is a yeast infection inside the pocket. If it was anal glands it would be a horrendous fish smell. Usually they express themselves while pooping...or if they get scared, startled. Orion has a malfunctioning gland that goes off when ever. It's gross. It's a liquid, not clear....almost yellowish. And you can smell it from across the room. The term we use here is "Ewwww! Orion fish butted on me again!"
