Birds, birds and more birds.  Not to mention a lot of squirrels.  There easily could be other critters but I don't see them.  We have lots of racoons around but they come out at night.  We have a few cats in the neighborhood (very few TG) but they all look fat and happy.  I really hate to see the cats outdoors.  This is not the country, way too much traffic at certain times of the day in the neighborhood.
