Food & Water:
There are so many food to choose from so no matter what one you choose make sure that it is high in protein because of how active ferrets are they need plenty of protein, some ferrets will over eat so you may want to remove the food over night. You need to have a secure food dish because ferrets are heavy enough to spill and knock them around you need to have pretty much everything attached properly and securely. You should have a secure water bottle and refill it constantly because ferrets drink allot. You can give your ferrets treats occasionally because if you give them treats too often they will get addicted and that is all they will eat.
