Hmm...let me think about this one for a minute. Ritzy has kind of a "time and place" thing with the bare skin issue.

She is more comfortable being held when I am wearing a big sweatshirt, but at night she cuddles up next to my bare arm.

She will only sit in my lap on the couch if I put a warm towel there first (spoiled spoiled spoiled)

She HATES sheepskin fabric stuff, which I find interesting because so many cat beds are made of this....come to think of it, the vet has that stuff lining the weight scales....perhaps there is a connection? (you know Ritzy, Catzilla at vets?)

Purr Padds, she loves....and I think these things feel like they are made out of the same stuff as floor scouring pads, itchy and nasty....but go figure, this is her favorite sleeping spot in the office... However, I put a purr padd on the couch downstairs and she won't go near it.

More research needed
