Speckles does the same thing. She meows and chats at all the flying objects going by. I'm on the 14th floor of a highrise and in the morning when I'm getting ready for work, the balcony door is open and she loves to sit out in her favourite chair and chat at the birds that land on the railing. Don't worry folks, she would never try to jump to get at them. It's too high and she's too lazy! I'm also right on the river so she chats at the seagulls too. Inside, she will try to catch the moths that fly in. Too funny!!
