get to your local pet store. Get a water bottle, and a bag of ferret food. Thats all they need really. Make sure they have plenty of shavings and loads of bedding. I use hay for mine and again it costs nothing. Ferrets can pretty much look after themseleves.
You can feed them cat food, rabbits ect they will eat just about anything. I also give mine a raw egg once in a while as it is a nice treat for them and it keeps their coats in good nick.
