I reccomend that you don't buy one from the shop. There are people and rescues with ferrets all over the country mate, look in the ferrets for sale section. Also you will need at least 30 purse nets, a ferret box, a large ferret proof hutch, constant food supply, bedding, and it would be a great idea for a locator and collar. Take your time and get well educated before you get a ferret because there is a lot more to it than chucking a ferret down the hole and then out pops dinner. Hope this helps.
