Cheers, Dolly - thanks for the ping! I used to have a cat who'd sit in front of the door all day, watching the squirrels and chipmunks scurrying around. She'd hunker down, put on her best ferocious-jungle-cat look and growl the whole time. The critters outside were deeply unimpressed. :)
the indoor kitties surely must have a fantasy world. All the treasures & adventures that are forbidden territory.
When I was first married & lived in appts, I could not let my kitties out, it was always a great source of enjoyment to watch them.. their little bottom jaws would quiver in anticipation as they stalked squirrels, birds.... I had one (not so bright apparently) who continually tried to go thru the window.
I now live where I can let my cats in & out freely & they are quite happy.
