A cat that has been run over so many time, you can pick him up and sail him like a frizbee.
" Yesterday a highway pizza, today a sail cat."
A dessicated and totally flat cat that has spent a few months lying in the road. When scraped up and thrown, it sails like a Frisbee.
There's a great sail cat in the makin' down on Dongbuster Road. We should go and get it some evening.
