mizombie,
Thanks for your comments. As you know, but others may not, I created the ferret in somewhat of a rush to try and help you out when you needed it. I am well aware that it could do with a certain amount of tweaking as I am far from unaware of what ferrets look like (and feel like) as there is hardly a week goes by without one of the little critters visiting. We have a neighbour who keeps them and they are always escaping from his garden and visiting ours. They seem to like us and have made friends with our cats and dogs.
I'm going to try Lyrra's suggestion and see if I can improve the model that way. If I can I'll let you know when it's ready.
Lyrra, Thank you very much for your advice. Yours is the first constructive criticism received. I find it sad that others choose to respond in a less than positive way.
