Thanks for the warning - I hadn't considered that might happen! Wouldn't let it put me off taking her obviously, but she really does seem fine so I think I don't have to take her to hospital.

Her head's fine, I've checked exhaustively. That's reassuring to know though, thank you! The mark on her forehead isn't even swollen and there are no bumps or odd bits on the rest of her head. I feel better for you saying that though, a medical opinion is always good. :)
