Thanks, everyone, for your help. I think I'll go ahead and make one. Our sofa has very wide (and deep )arms. I'll probably sit the bed on the back corner of one end of the sofa, which is Puddy's favorite spot now, as she can watch the birds out the window there. As long as the bed is in one of "her" spots, I think she will use it.
I was thinking that having an actual 'bed' for her might contain some of her fluffs of fur which occasionally extend off the towel. Frankly, I'm tired of dealing with the fur, but my ds and dh are crazy about that cat, so whatcha gonna do, huh? :roll:
