The only time you'll see the feral side of Bond is when he is having raw meat. I went to a farmers market today and there was a raw pet food lady there so I got some rabbit shoulders for them. Milo couldn't be less interested, Dougal eats everything with the same non-plussed enthusiasm and bond swoops in, grabs the spils and runs off to eat in peace. He ran to the hall (whole three feet from the dishes) and proceeded to have a good chew. But if any of the others even look at him he grwols like a cat possessed, it sounds very threatening but I have witnessed Dougal waltzing up and nicking his food, Bond doesn't try to stop him
So his growl is far worse than his bite.
