What Could They Be Staring At?

They're watching the trees and the butterflys and the bugs flying and the grasshoppers hopping into the pool when they should be in the grass. They're watching the ants crawling up the side of the house next door and the postman walking down the street delivering mail. And they're watching the kids playing basketball on the playground across the street and all the other kitties playing in the back yard. They're watching the trees shake in the wind and the birds flying about. They're smelling the cool, fresh breeze coming off the lake in the distance. They're watching the boats pull up to the dock. If they're not watching these things, what else could they be staring at?
