The Ground Go?!?

I meant to post this yesterday, but I forgot. Sunday I was in the computer room on Monika's desk and Bob raised the blind for me so I could look out the window.  There was a lizard on the screen  so I jumped down on top of the covered litter box and then climbed onto the window sill to try to get it.  I was have fun chasing it until it ran quickly across the window.  I turned so fast trying to catch it that I lost my footing and fell off landing next to the litter box.  Bob and Monika both checked to make sure I was OK and then they said they were going to have to look into getting one of those kitty window shelves so we have more room to turn around when we are chasing window visitors.
