Ferret-proofing is essential before letting your ferret roam outside its cage. Ferrets are curious, flexible, and persistent, and they can squeeze through openings as small as one inch, climb into furniture, and ingest dangerous objects in seconds.

Start by getting on the floor at ferret level and scanning for gaps. Block spaces under doors, behind appliances, inside cabinet kickplates, and around pipe openings with hardware cloth, foam pipe insulation, or plexiglass panels. Check along baseboards where small gaps may exist between the wall and floor.

Remove or secure all rubber and foam items. Ferrets are strongly attracted to rubber and foam and will chew and swallow pieces, which can cause life-threatening intestinal blockages. This includes shoe insoles, rubber bands, ear plugs, remote control buttons, foam padding, yoga mats, and erasers.

Cover or elevate electrical cords using cord protectors or cable management channels. Ferrets chew cords both out of curiosity and during play, which can result in electrocution or burns.

Secure heavy items that could topple. Ferrets climb and burrow into unexpected places, including behind bookshelves, inside reclining chair mechanisms, and under rocking chairs. Reclining furniture is particularly dangerous and has caused many ferret fatalities. Consider removing recliners from ferret play areas entirely.

Block access to houseplants, many of which are toxic. Remove or secure trash cans, cleaning supplies, and any small objects that could be swallowed.

Check window screens for security. Ferrets can push through loose screens and fall from heights. Keep toilet lids closed, as ferrets can fall in and drown.

Always supervise playtime even in a ferret-proofed room. Ferrets are remarkably inventive at finding new hazards. Rotate toys to maintain interest and provide tunnels, dig boxes, and interactive play to keep them mentally stimulated and less focused on destructive exploration.

Do a headcount before closing any doors, drawers, or appliances. Ferrets hide in laundry piles, dresser drawers, and even dishwashers.
