Phineas, my orange and white tabby was laying in front of the glass doors making this strange chirping noise... his tail was fidgeting back and forth in obvious excitement (perhaps impatience?). I walked closer to him, and normally he notices this, but he was far too enthralled in the chirping to look away. Outside were some birds... one in particular was chirping in time with the cat. The cat would chirp, then the bird, and then the bird would hop closer.
When I approached too closely, the birds flew away, and Phineas got up in a 'ready to bounce, but I change my mind' way.
Was he really luring the birds closer? I haven't had him for very long and he is 5 years old... perhaps he's learned this trick earlier in life?
