How do I help this cat?

[Tobi]

She loved her igloo bed and wouldn't go near anything else! Now she loves her polar bear bed and won't go near anything else! When I visit at night, she eats, then goes on top of the radio for a wash (we listen to classic FM on low volume. She's OK with that unless it's Bernstein or Stravinsky....she handles Wagner -unlike Misty.) Then she gets into the polar bear bed, I pull the top over her and she falls asleep. After a little while I creep out and go home

Sally Cat is so funny and she is such a typical cat.  I bet she suddenly changes to a different bed with no warning and no obvious reason. You will be left wondering what happened. Cats like to keep us guessing.

Wagner is an odd choice for a cat. I would have thought it was to wild for her.

How does she feel about Vivaldi and Pachabel?
