The lawn dried better, faster than I anticipated. So, I mowed the back first and have let the cats outside. I'll do the front tomorrow. Watching the cats out back, I noticed that they seem to be shy. I get the impression that they might have been inside for so long, perhaps close to two weeks, that their instinctive homing device might not be set any longer, as they seem to be re-familiarizing themselves with the patio and the back yard, so that they can later identify it as home. I am a little nervous.
