In my desire for efficiency and certainly not out of any good sense, I arranged for Brinker and Huckle to be seen by the vet at the same time. This was the first time he's been to this vet, and he was overdue for a check. When I made the appointment, I warned them that he would likely be cantankerous, so they noted that with a "caution" on his cart.
He howled all the way to the vet. When we arrived, the tech noted the caution, and went to gingerly open the crate. Huckle was fine. She reached in to pet him. He was fine. I took Brinker out for a bathroom break, and when I got back to the room, Huckle was wandering around in a worried but non-aggressive fashion.
When it was his turn to be on the table, he was fine*. When the vet checked his teeth, he was fine. When he listened his heart, looked at his ears, felt his abdomen, he was fine. When he gave him his shots, he was fine.
*I say "fine"; Huckle says "at the gates of Hell"
My husband and daughter couldn't believe that the cat who lies in wait to attack my husband could be so docile in a very stressful situation. It just goes to show you. Way back when I had my trio of cats (Bianca, Keeper, Buster), it was my sweetest & most bombproof one, Bianca, who got the (deserved) caution note at the vet .
