It appears to have. I mowed the lawn -- front and back -- last evening, shortly before sunset. It was hot work nevertheless. Once it was done, I went inside, relaxed a little and made dinner.
Afterward, I went back outside on an errand and looked around for the Great Gray Slugs -- and found a pair of them on the privacy fence! They are medium-sized as such slugs go, a little more than finger-sized, and didn't like my taking a flash photograph: they froze in place for a minute, then resumed their slug business, whatever it was.
Still later, I was in the kitchen getting a bottle of water before bed, and motion in the back yard caught my eye: a couple of fat but not too large raccoons were sorting through the freshly-mowed yard, catching something, pouncing after more, and generally looking very pleased. I tapped on the window and one of them gave me the fishy eye as only raccoons can -- not especially challenging, but clearly a, "Whaddya want? We're working here!" sort of look.
