Ever since that time...

   ... of Maybe's visit to the vet's where she was diagnosed with fleas, and medicated for it, and since we had the carpet cleaned, and she was banned to the playroom for a period of time, she now refuses to walk on the carpet. To get to the couch, she'll go over the divider and walk along the tops of the furniture. My kids used to do that when they were avoiding the piranhas  on the floor and the grandsons climbed the furniture to avoid the hot lava.
