Randy chases nothing. Nothing chases Randy. Randy has been infected with Cat-itis. He lays around and sleeps most of the day, and occasionally commits a rudeness that he blames on me or a handy cat. He is SO overworked. When pushed, he protects his territory from other dogs. And then goes back to sleep. Leaving me to hand out my vet's card with a note on the back that says: "fix it, I'm good for it. signed"
