I would guess he has jumped out about 20 times in the year I had him. The stress of doing that hasn't slowed him down at all. He has eaten with cat hair still stuck to him. If I open a panel for any reason, he is right there to investigate. If you can make a feeding hole I would suggest it. I have had a jar and a silver and neither one ever touched the floor. One neat feature of these guys is barbel placement. He has never damaged his even though he is always banging into something. My silver was always breaking his. The jar did sometimes.
