I cleaned the carrier last night and put it together (without the door), put a towel in the bottom, and tucked it in the back of my closet. It fits exactly in the end of the clothes rail part with part of the entrance covered by the "linen" shelves. Enough room for even Shiva to get in, but a bit more privacy. Spirit looked at it by herself this morning and I took Giorgio in and showed him. He went back later and stuck his head in again. I'll have to point Shiva at it soon. I put a handful of snackies back there -- they have good noses, so they'll probably smell them from the bedroom.
I brought the impeller in from the fountain and cleaned it and the hoses. They're drying in the dish drainer now and I plan to take them back out to the storeroom for the winter when they're dry. The leftover paint is blocking the center space in the storeroom and I have a place to put them in there, so when we get a warmer day, I'll do that.
