Mine do this and I’ve tried a few things, to no avail. At first I was afraid too, because they were biting the paint off and now the bars are bare. I tried putting things on the bars that made them taste bad, but unless I did it to literally every bar it did nothing - they always found a way lol.
All I can tell you is that it’s hopefully ok - my babies never got sick, and the only problem I ever had is that now my bars look terrible lol. They do it every time I wake up, want a treat, or just want to be noticed, and I know a lot of other Piggie Pals have the same problem. The only bad thing to ever come of it is that they occasionally break their teeth doing it, which is fine because in 2 days they’ve grown back.
Is there anything in particular that you’re afraid of?
Also, Piggie Pals - have you ever found a way to remedy this??? Again, I know it’s something we share in common a lot lol, but has anyone succeeded in stopping this behavior?
