I used to let Ragnarok roam my home, when I lived in an efficiency one bedroom apartment, (nowhere to escape or get lost). I once let him roam for awhile, and when I started to look for him, I found him 7 feet up the wall, hanging on the edge of the electrical panel. I didn't think it was possible he climbed the wall, using an ⅛ inch of grip with is belly scales! Balls are very proficient climbers! I wish I had a picture, because it looked like he was just hanging on the wall by super glue! I freaked out and grabbed him off right away, thinking he would fall or hurt his belly scales, but that was the day when I discovered that he loves to climb.
