I'm going away for a week and set up a webcam so I can see how the
boys are doing (of course a cat sitter will be by daily). Yesterday I
had it focused on the cat tree. I looked in from work every hour or so
and twice saw one in the tree. So today I set it up to watch the
platform by the south upstairs window. Early this morning Espy was
there but nothing since.

Where do they spend the day? Downstairs partying with the local
putties? Maybe on the bed? For tomorrow I'll set it up watching across
the bed and trying to catch the platform. That should do it.
