A major group that the cats have displaced (if not in space, in attention) is our large plush animal collection. We have ~ 100 creatures, mostly bears, on shelves around the place. Collected over 15 years, they are in excellent shape, since of course we have no human little ones and the cats mostly leave them alone.
With the ongoing space issues at the kitten farm, we made a decision last winter to give away many of the plush creatures. With the destruction from hurricane Katerina, this has become more urgent. We've basically been looking for a place which accepts gifts in kind for the youngest hurricane victims.
The Boston Globe had pointer to a collection going on at Foxboro Stadium tomorrow, so 50 or so creatures are leaving us, to lead lives snuggling kids who need them.
However, although we had too many bears even before the cats arrived, it does make me sad to see them go.
