Yes, we did.
My husband and I brought one of the two abandoned cats to our bookstore. We'll keep the little bruiser there for the winter months. The other cat, Gracie, (we started calling them George and Gracie) is holed up in a large-ish hollowed out piece of foam insulation (actually it looks better than it sounds) and seems to be okay staying there at night. She crawls out in the mornings and runs through the snow to my front door for breakfast.
I'm crossing my fingers that both arrangements will work out for George and Gracie!
ETA: Our landlord at the bookstore has told us we can't have a cat there. So after four days we had to bring him home. It's too bad because the cat had got quickly used to the store and people seemed to like him quite a bit. Well, back to the drawing board.
