She finally got the collar off, but by accident I think, when she was having a scratch, the clasp is non to sturdy anyhow. I put it back on her but it came off again the next day and this time Bobby got a hold of it. Managed to trade him for it with a Bonio biscuit and the tag is fine, he didn't do any damage to it.

Have to get her a new one with a stronger clasp.
