My female kitty likes windows.

The area below my window is just grass, so I'm not scared of her falling, though I'm sure she will eventually.

My kitties (5now, had 12) are all like that aswell. they see birds and get all angry and then scared and then repeat.

Thats beastin, my dog likes windows lol. My cat doesn't really like em, but we have a small table near the window that he will jump on and look out the window for a little bit and then just go away because he gets bored with it. However, My dog though, she will sit in the window all day if she wants to
