Remember how scent driven cats are. As Precious had urinated in the box, it's no surprize new puss didn't stay long. And if Precious prefered the larger bed, then the previous one won't smell of her, so much, hence kitty's preference. I don't mean to sound critical (as I'm definitely not being) but, in an ideal world, all previous items should be changed for new, in order to remove scent traces and help the new puss settle in. We usually donate items to the Center - they're always after things! (and, yes, I know how fortunate we are to be able to afford to do that...). Apart from special mementos, that's what we did with Meowser's things, so that we're ready to go when the time is right (keeping or fostering).
