There is a war on between my cat and the backyard birds. I call it Angry Birds vs Angry cat. My cat hates birds. She loathes them. The birds feel the same about my cat. I can always tell where my cat is by the sound of the angry birds chirping at her. They drive her nuts as you can see. She talks to herself when they tick her off. The birds have a major advantage in this war; they can call in air support. The birds have stealth Kamikaze dive bombers that swoop down silently from behind and drive my cat nuts.
The back yard is like watching the Military channel. No need for TV.
