Good post. Your description of different vets and clients reminded me of a story: the time I took our cat Calvin (RIP) to the vet for a yearly checkup and he had to see a different vet who turned out to be their Large Animal guy instead of Calvin's usual dog and cat guy.
Lol, this vet was all business. Caring and concerned in attitude, but he surprised me (and Calvin) with how rough and tumble he was, spinning him 'round on the metal table, sticking the thermometer in, spinning him 'round again to check his ears and eyes, pushing his mouth open to look in there, lifting him by his haunches to feel his insides, spinning him 'round to look him over again generally, etc. There wasn't any of the usual gentle prods and pickups which our cats have grown used to complying with. It was a little like watching a guy make pizza out of a dough ball.
I looked on a bit aghast but he wasn't actually hurting Calvin (at least that I could tell). Calvin seemed a bit stunned, is all. Maybe this vet had a domination thing? Calvin was used to "chatting with the techs" (as his vet told me) while in the back if they had to take him back for a test. He was a friendly and gregarious cat who liked people. No domination necessary.
I checked the vet's name so that we wouldn't see him again except in emergency and that's where I saw he was their Large Animal vet. Then it all made sense....I supposed by comparison to his usual patients this cat was a flea. But it made me feel bad for the cows!
