Here is where I found the basket part like it, Amazon search for this; ONOR-Tech 2PCS 3 Tier Hanging Mesh Storage Closet Toys Organizer. Then you can add goodies to it.
Well look at that...a cage made out of a inexpensive metal shelving unit and hardware cloth!
Small Pets DIY... Ferret ball pit made from plastic Easter eggs. I got 144 of them from oriental trading for $10 The eggs are also great for balls to roll around when you put beads or beans in them.
DIY Rat toys. Most things on the list can be made in a larger scale for ferrets (Note: the cakes are not ferret-friendly, do not feed fruit, or bread, to ferrets).:
Ferret Central. This is the most awesome cage ever
Bean dig box for ferret
Ferret Cat Shaky Pill Bottle Toy! (1/2 Dozen)
Pet Hedgehog... I might leave out the gems, and sub in rice for sand and some packing peanuts.
Homemade Safe Ferret Food
Cheap and would keep the ferrets occupied. Need to think where both end of the pipe go to though.
