Okay, so this thread is yearsss old, but still. Reason I'm posting here, is because I was looking for information about these holes before starting a new thread; my pb only has two of them on one side of his jaw, and I initially freaked out when I found them. He's young, and I got him over a month ago, only noticed the holes about a week or two ago.
Since this thread is so old, could anyone post an update on how their balls with holes are doing? Hope you read this, I'm very curious!

PS I keep him in a terrarium instead of a rack, so I guess the rack-theory doesn't apply here
