No way would it be possible , even if i had my own mansion with a huge hall i still wouldnt be allowed to hold a show, it requires a license from the local council ,plus now we have new animal welfare laws which is seeking to stop all animal fares , a recent bird fare was stoped a few weeks ago , the only way it can happen is if all animals there are exhibits only and will/cannot be sold.
there also trying to ban animals being sold on the internet , the uk has seriously gone down hill imo there wont be a reptile business possible here soon.
the trouble is are government and councils do not want trouble (cant be bothered with the hassel ) with AR groups so these animal rights groups and the R.S.P.C.A are winning the NO PETS battle they always wanted
