Actual conversation at the vet's with Hyperion this morning:
Vet Tech crouches down and unlocks cat carrier, looks at Hyperion and says "Come on kitty," then looks at me.
VT: Is he deaf?
ME (taken aback): No, he's not deaf...he responds to...loud noises.
VT: Oh, because most white cats are deaf.
VT: Yep, white dogs too. But Hyperion has yellow eyes instead of the blue, that might have something to do with it.
This next part doesn't have anything to do with the post title, I just thought it was funny.
VT then lifted Hyperion to take him to the scale. VT: Oh, my gosh. He must have some Maine Coon in him.
Maine Coon cats can get to be 35 lbs. And Hyperion's much-postulated weight actually is: 18.9 lbs.
