Both Livvy and Cassy have 'door dashed' in the past and it scares the hector out of me.

Usually it's Cassy (my lunatic silver swirl tabby male) who gets out. The most recent occurance was Saturday evening as I got home from the cat show.

I hate it, I really do. But chasing him seems to make it worse, so now I just open the sliding glass door on the patio and let him come home on his own. (Okay, we make interesting noises in the kitchen and that usually brings him home sooner. Usually.) Saturday he was out for an hour.

Livvy hasn't figured how to get outside from the patio -- the railing is waist high and there's shrubs. Cassy can vault both, but is faster than I can catch.
