Hello all this is the first time I am writing so excuse the misspellings. There have been a few questions on caging and I thought I could help. my husband and I built our own cage. we used 1 inch wire (bought at a feed store), the lumber form homedepot. the shelves we made out of plywood and we first covered everything with indoor outdoor carpet...big mistake. Fancy our deaf little angle dug at it constantly until I was to nervous to leave it in(afraid she would eat it) so we ended up covering all the shelves with linoleum...works GREAT, easy to clean if they have accidents and they dont chew it. someone asked about tubing. I went to homedepot and in their plumbing section there is black tubes used for irrigation. I has air holes and elbow joints and many other connections which give you alot of options when putting them together. yes you cant see them but they enjoy it and it is easy to clean. we first had the clear plastic tubes which they destroyed. some one asked about there deaf ferret and tubes, mine does fine. I hope this helps. Laura, Josh (the hubby), Squirt (the chubby one) and Fancy (aka Fancy Pants, the deaf one) P.S. I agree with Paula and gang about getting back to what this fml is for [Posted in FML issue 2720]
