Ferret proof your home and know it really isn't very ferret proof.... these little fun guys are always looking for a way to have fun, usually meaning trouble :)
Guests , Children and doors are dangerous to our fuzzies.

 Remember if they can get their head into it, they can get their body through it too!

see House Proofing

Cages preferably a large one you can always section it off to make it smaller but you wont be able to make it larger. Some you can join together to make them larger but its an expensive way to do it.
Why is larger better ? Ferret Math is NOT a myth

Food have you looked around to see what is available to you in your area. If you cant find a good quality ferret food there are online ferret/pet stores that you can order most quality brands. Remember if there is fish in the food you will get smelly poops.
Take a look at my ferret food breakdown.

Litter boxes and litter. High backed and large are best but here we use several smaller litter trays that are easy to get in and out of the cage without having to pull it apart. After trying many different sorts of litter we are now using Alfalfa Rabbit Pellets for several reasons...... if the ferrets digest some it wont harm them, they put of a pleasant smell and they are cheap.

Treats. Raisins, Banana no more than 2 pieces a day.  Ferretvite, Ferretone one or the other given daily.
