Since I have trouble looking up into the tops of trees to see birds when Sydney and I go out with our binoculars, we recently bought a CD of bird songs so that we could start memorizing the more common birds in our area. Since the CD has something like 360 species on it, I think we have a ways to go. But when we start playing the songs, Arwyn goes nuts. I think she’s realized by now that there aren’t actually birds in the house, but she still gets very affectionate, rubbing herself against our computers (where the sounds come from), walking ’round and ’round our work table, and looking longingly at us, hoping we’ll produce something she could chase. I think our local humane society would call this cat torture, but we’re hoping it’s something more along the lines of cat education.
