I put Leo in his xpen, because he wouldn't stop chewing on the rug. I had my back turned, and heard a rattling sound. Looked back, and saw Leo at the very top of the pen. I rushed over to grab him before he jumped, and before I reached him he fell back and landed on his side. He started yelping, got up walked a few feet and kept yelping. He stopped yelping and just stood there, then he started to wag his tail. He doesn't seem to be limping or anything, so I put him in his cage, and headed back to work. My Grandma is going to check on him when she gets there. Should I call my vet? He weighs 3-3.5lbs and fell from about 4 feet.
