I finally got around to doing a project I had been pondering for some time... adding a separate litter box chamber to my weasels' cage. It worked out pretty well! You can see pics and read a walkthrough here: http://wrongcrowd.com/gallery/misc/DSCN5020 Just click the forward arrow to move through the pics. Once I attached the add-on, I covered the floor with bedding so they wouldn't want to poop there. I also removed most of their hammocks, to force them to sleep on the floor in the no-poo zone. I'll put the rest of the hammocks back in a week or so. I am happy to report that the critters took to the new accommodations right away. (It probably helped that they had been using that litter box already in another place.) Approx cost: $70 Breakdown-- Blast gates: $5 x 2 I got them at Amazon but if I was doing it all over again I would place one order at WoodZone. (see below) http://www.amazon.com/exec/obidos/tg/detail/-/B0000223YR http://www.woodzone.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=WOS &Product_Code=828922 Litter box: $8, local pet store (I could not find a plastic tub that would fit a high-back corner litter box so I used a square one. I think it is a SuperPet.) Plastic tub: About $15 at Target Nuts, bolts, washers: $6 from Home Depot Flexible hose, quick-disconnect fitting and clamps for the blast gates: $31 at WoodZone.com. Here are the part numbers and prices from my receipt. I don't NEED 10' of hose, but that is as short as it came. I will use the excess as a toy for them. I also don't know if the quick-disconnect fitting will fit tightly enough to be weasel-proof but I thought I would give it a try. Code Name Quantity Price/Ea Total Price/Ea.
