It looks like Ali is pretty calm, even though at the vet. Silly is that way, too. She has never growled at or tried to bite Gina, even though Gina had to dig in her mouth to take a piece of string out from between two teeth.
One of my cats is calm too, but the other.. a total nightmare. Hissing, spitting, biting, growling and yowling.. it takes the vet and 2 techs to get him sedated so they can examine him!
