Oh, gawd, the vet racket. I'd heard of that book... it doesn't seem to be available as an ebook, though?
Current struggle with the vet: "Oh, your cat gets carsick and you're moving? We can prescribe tranquilizers! Oh, but his blood tests are two months out of date! You'll have to bring him and, and we'll run them again (total cost: 250$), and then you can have some tranquilizers for the cat!" Or, alternative: the cat can be out in a nice waterproof carrier, puke on himself, be washed an hour and a half later on arrival, and not be moved again. An hour and a half of cat misery is NOT worth 250$, wtf.
Also: "Oh, of COURSE your indoor cats who never come into contact with any other animals because they are terrified of the outside world need to be vaccinated every year against illnesses that are spread through contact with infected cats! That'll be 150$" (Yeah, no.)
I've had MUCH better luck with country vets (whose primary business is cows and pigs, and are used to farmer attitudes towards animals) - when they treat cats and dogs, they're typically decently priced and don't recommend useless treatments. City vets used to only treating cats and dogs, though? Ye gods, the mark-up. And all of a sudden thousands of tests are necessary for any small thing.
