Torn out nail??

[Holly]

My friend's hamster, Tinsel (who has been pictured on here before when he's been staying for his holidays) has apparently managed to pull out or bend back one of his toenails. My friend will take a picture today for me to post here as I'm not sure what she should do about it?

I've told her to watch him closely when he comes to see if he's running and climbing normally or if it seems to be bothering him. I'm going to send her the nail clipping article but I'm pretty sure his nails aren't too long as he only left here about 3 weeks ago and they weren't then.
