Wow...I've never seen a black & white with that pattern! Thanks for attaching the pic.
My tortie was very sweet and gentle at home but terrified of the vet. She could be tough for them to work on, if they weren't careful to be very calm & quiet around her.
My black & whites are all very sweet loving lap cats who purr at the vet, except for the oldest, who is sweet most of the time but can get a little cranky occasionally. They're all very demanding of attention, and always want to be where I am.
