Thank you for your advice Rambler, much appreciated. To be quite frank, I thought that I had acknowledged this in my post to Bigfoot at 15/23. I had just looked up weasel in the Chambers Crossword Dictionary and found the reference to "wolverine" therefore assumed that it was appropriate. Bigfoot's request was simply for "Weasel like animal" not an animal that was the same size or looked similar to a weasel. Since the wolverine is related to the weasel I must assume that it will share some of its characteristics. What I can't control however, is if people want to go off on one!
I hope that this clarifies the matter. All the best. Andy
