That is fucking outrageous and I have no idea how they have the bare faced cheek to charge these exorbitant prices. I am sure that someone will be along soon, to say 'well look at how much HUMANS cost for medical care lalalalala.' Save your breath. You can't compare pets to bloody humans. No WAY are any of these prices/breakdowns of the prices even remotely acceptable.
We had pets when I was a child (late 1970s and 1980s,) and always had a dog. No way was there EVER a bill that high for ANYthing. Not for anyone. It would never have been paid if there had, as no-one could have paid it as most people were brassick, didn't have access to credit, had very little savings, and would have surrendered the pet.
Someone will no doubt come along (also) and say 'but the treatments are sooo much more sophisticated now and pet vet-care has become so much more exquisite and intricate with fabulous new technology etc etc etc.' It's no more advanced now compared to the 1980s, than it was in the 1980s compared to the 1950s etc, So put that chestnut pack in its box!
I think some vets know that people have more access to money now, and better pay maybe, and that they will pay it. (Somehow.) Sure you can get pet insurance, but some conditions aren't covered, or even if they are it's only for a short spell, a year maybe, and also you struggle to get pet insurance for pets over 8 years old.
My cat's insurance TRIPLED when she hit 8, and I rang up the insurance company and said 'I am not paying that! Surely you can do cheaper!' She said 'that's it sorry.' I said 'well I will cancel it then.' She said 'sorry to see you go, have a nice day.'
Didn't give a shit that I cancelled. Didn't want an old pet registered that's all. I mean God forbid they may have to actually pay a decent amount out! 
We have one cat left (aged 16.) When she has gone, we will never have any more pets. The vet fees are extortionate. And we have the preventative care (her yearly jabs/worming drops/flea drops,) and we have also had to pay multiple 100s (running into a couple of thousand) this past 2 years for dental work and things that were wrong with her ears.
Never again. As I said, vet fees were NEVER this expensive. It's scandalous! Nothing anyone says will change my mind. If people don't want 'vet-bashing,' as someone said earlier, then get them to drop the bloody prices!
Utterly disgraceful what some of them charge.
