I have only bathed my pigs one time, right before they moved into their new cage. They were all stinky from introductions. Now Scooter has taken to laying in the tubes where he poos and pees and his under belly is all icky. I clean the tubes daily, but unless I stand watch 24/7, he's going to get dirty. He has longer hair so it really makes a mess on him. My question is would it be ok to wash his belly, only his belly, when it gets gross? That would probably require a partial bath 2 or 3 times a week. I'm really hoping he'll grow out of it since he's just a baby right now.
