The first time I got bit was by Ranen. I had just had surgery (gall bladder) and so I hadn't been able to check on him in a week. When I opened his cage I saw his shed, his poop, and him. He was PISSED! So I used the lid to his cage as a kind of shield to attempt to clean his cage without having to touch him. Didn't work. He was SO fast and he struck under the edge of the lid and tagged me in the webbing between my fingers. It didn't even hurt. I looked at him and said, "You just bit me!" It bled a little but required no band-aid and the next day it was fine. The 2nd time I got bit was by Oscar. It was feeding day, but he was under his paper. So stupid me reached under his paper to pull him out and he clamped down on my finger. I was NOT expecting it so I pulled my hand back and he came with it! It stung a little and bled a little but it was fine. That one really was dumb on my part. I learned my lesson! He's a pistol on feeding days, keep your face and hands BACK! He's struck out at my 4 y/o DS's face before on feeding day. Any other day he's a puppy dog and he's never struck except for when he's being fed. Watch out!
