Animals Act 1971 (Amendment) Bill

I was trying to make the point that the majority of domestic animals might live in a state of nature in their natural lives, but in many cases they are shaped and formed by human beings, so are we considering an inherent characteristic, a formed characteristic, or a shaped characteristic? Once, when I was interviewing one of my constituents, he allowed a ferret to run across the desk, and it bit me. Apparently, that is an inherent characteristic of ferrets when meeting Labour MPs. Equally, however, an animal could be trained against its nature, so how could we possibly attempt to define the characteristics of an animal?
