ferret proofing oh my. It takes some good practice & even to this day I goof up once in a while. I move a chair just 2 inches to the left & bingo they can hop onto the table, etc... just simple things now. Although at first I did have 2 escapes to the outside world SCARY! Ferret proofing is never ending.

Just stay away from any materials that can bitten off & swallowed (rubber soft plastic etc..) as ferrets can get blockages very easily.
get down on your hands & knees & crawl around your whole house. They are like rats, if their head can fit so can their body. Watch out for places like under cabinets, stoves, refridgerators washers, driers etc... as they can get lodged under there, or ooyu could have a hole under there or they can crawl into the appliance.

Ferrets do not have a cecum which is what digest all non-meat foods, they are 100% carnivors, they can properly digest abything but meat.

anything else just ask or pm me!
