What do you suppose is eating them?

Blossom and Sunshine on a pretty fall day. I can't quite figure out their expressions other than they don't like the camera.

Some more progress

I'm pleased to report that twice in the last two weeks Sunshine came in for the evening off the deck on his own when I opened the door. Were still pretty far from him using the dog door however. He also managed to tolerate being in the house while we had some work people here. At first he didn't but after a few weeks he got used to it. Very pleased!
