You do astound me
Wolves in Bedfordshire ( from the article) There is the Anglian Wolf Society,
open to the public on limited days, I'm not quite sure what they are trying to do TBH, they claim "conservation" but while they are imprinting them, its hardly conservation.
Having spoken to a few that work there, the miond boggles as to what they are trying to achieve save raise funds to buy more wolves to breed and imprint to raise more money to buy .... well you get the idea
I used to own 2x 16 foot Indian ( Burmese) pythons that I raised from hatchings, They'd give you quite a nasty hug should they be so inclined.
No licence required, I've had a few other "bits and pieces" in the past, when you could still import various exotics, well before there was the need for DWA licence(s), CITES or anything else.
Consider this, you breed them for a few generations, and have kept them for years, and no one knows you have them.
Just don't take the Cheetah down Tesco's ( I know it says no dogs, but it doesn't say no cats

)
