Mr. L has fabricated a cat feeder hold down. After a week in service, nobody has tossed it yet. One kitty investigated.
I also changed the orientation of the doghouse in hopes of catching if anyone goes inside. Kitties, as you know, are curious.
Finally, the birds are using the feeder too. I thought they might not need the birdseed with all the spring stuff in bloom. This mockingbird, as well as sparrows and cardinals, seem to disagree.
