What a brilliant idea!!! I've had several moves over the years and have never thought of that one- great suggestionSince you are moving soon, let me suggest taking an OLD sheet, and spread it over a favorite napping spot for them. Just before you moved, cut the sheet into squares, about 18" (46-ish cm), and fold the squares, fur side in. Take them with you, and place a few in every room of the new home. THEN release the cats. They will smell themselves everywhere they go, and it will give them "instant" territory. They'll still have to adjust a bit, but familiar scents, especially their own, will make that easier!
