QUESTION: Roger has started to run from one end of his cage to another. He can keep this up for a good 30-40 minutes. With only about a 20 second break here and there. I first noticed him doing this after he got his antibiotics. I seemed to be in the cage (floor) with him when he started up. But once I was out I went back to check on him and he was still going. I thought he was having some sort of a reaction to the medicine. He's been off antibiotics for a week now and is still doing it. Why would he be doing this? I think possibly the anesthesia did something to him just because it started after surgery. My husband thinks he may be getting all his senses back and possibly smell the two new baby pigs(boys) in the house. They are clear at the other end of the house. I've researched and can't find anything suggestions as to why this is going on. Any ideas?
