Let me introduce you to my favorite gardening link, You Grow Girl. It's really charming, even if you're not a gardener. There's lots of pretty images, and I found the following in the forums in a thread about animal life in the garden:
"Though every now and then we get some very loud birds and my little kitty listens to them and makes sweet "I want to eat them" mewling noises. I think those birds know she's there and are taunting her!"
