Poor Minnie. She took going to the vet quite stoically - she was a bit annoyed to be put in the cat basket, but soon settled down and just peered out of the windows looking a bit cross as I drove there. While we were waiting at the vet I put my hand in and stroked her until she relaxed a bit and purred, then when we went in, she was a bit cross but resigned as she was poked and prodded on the table with me stroking her to keep her calm. She yowled and tried to escape when it came to having a thermometer stuck up her and then the offending gland manually squeezed out by the vet, after which she shuffled to the edge of the table that butted up against the wall and tried to curl herself into a tight ball, but didn't try to attack myself or the vet. After being put back into the cage she soon settled down again, albeit now much crosser, but when I got home and let her out next to her food bowl, she hopped out and started eating, then was perky and happy again.

I've seen cats fight all the way to the vet, constantly try to escape, then when released go and cower behind a cooker for the rest of the day!
