I agree with racing hamster about getting the vet and if possible using this thread (or email) to send to p@h as evidence, or even sending it to the manufacturers as evidence that their safe wooly stuff is in fact not safe, something ham owners have been arguing over for years.
I am so pleased your lil one has made a full recovery, poor lil boy. There's nothing worse than a sick ham. I bet he doesn't know he's famous by having a sticky thread!
