Hi Walter, we don't know what he is, but he's not a bobtail by choice. He's wild and adopted us the day we moved into this house he parked himself in front of the back door and watched us. I put some food in a dish for him and we've had the same ritual daily for 6 years now, but he keeps his distance. I named him 'Anthony' after a song by Little Anthony & the Imperials (yes, I'm that old) called "I'm on the outside looking in". Then, about a year ago he showed up with a broken tail, most likely had a narrow escape from the coyotes (as you can see, we live in the hills), and about 3 weeks later it finally fell off. Then Hubbeee started calling him 'Bob'.... I refuse to give up 'Anthony' so he's become 'Anthony-Bob'
