Xiombarg has had an arthritic hitch in her shoulder for a while now, so when my mom offered me a heating pad as part of her divestiture-of-stuff, I accepted it. It has a nice flannel cover, I figured the cat would take to it pretty rapidly.
So I brought it home and put it on the rug-covered box she hangs out on when I'm on the computer. She wasn't having any of it - wouldn't sit on it warm or cold. So I tried it under the rug, to see if she'd find the warmth plus familiar rug attractive. Nope.
So this afternoon I stuck it over on the bed - and here is the kicker - as though I were going to use it myself. Lo and behold, she's been curled up on it ever since.
