How can I stop my human hauling me off to the vet?

Dear George,
Periodically, my human will ambush me without warning (usually when I am sound asleep enjoying dreams of chasing mousies and birdies) and stuff me unceremoniously into my PTU and cart me off to the dreaded v-e-t! There I am subjected to all sorts of atrocities -- loud, barking dogs in the waiting room, having to sit on a cold metal table in the exam room, having my teeth and ears checked, and the worse one of all...getting a shot in the butt!
What can I do to get my human to show a little common courtesy and ask me first whether I would like to be stuffed into my PTU and carted off to the v-e-t to incur all those atrocities?
And when she doesn't take NO for an answer and carts me off anyways, what, if any, recourse should I take against her?
Sincerely with a sore butt,
Wally

Dear Wally,
You have put your paw on a very sore issue indeed, one of the most outrageous examples of human stupidity even human cruelty. It is the sheer hypocrisy of it, that gets up my gleaming black nose. One moment the human is cooing all over us, then suddenly they are taking us off to what is a torture chamber. How can they do this?
So what can we do about it? The first thing is to brush up your verbal skills in human language. Like the rest of us, you probably stop listening to their endless vocalising. They never stop "talking" so most of us cats simply screen out the noise. However, this is a mistake when it comes to the v-e-t situation. You simply have to keep an ear out for that particular vocalisation.
It's not alway easy. The word comes in the middle of a torrent of other similar sounding vocalisations like "pet" "yet" "vat" "vit'amins and so on. However, if you apply your considerable cat skills to the task you will find that you can hear it. Once heard, the word is an advance warning.
Make yourself scarce immediately. If you are an outdoor cat, this is the moment to saunter through the cat flap and disappear for the nex 24 hours. If you are an indoor cat, it is a little more complex but there are places from which she will find it difficult to extract you - the furthest side of the bed, underneath the cooker, behind the fridge, high up on the top of the wardrobe, inside one of the drawers in a chest of drawers.
If these places don't work, think laterally. The point about the human species is that they are relatively unintelligent. I have found it useful at times simply to hide myself by sitting on a chair that has been drawn up to the table - ie: I am hidden by the table itself. This is a particularly good place if your human has a tablecloth over the table. I have seen my human running up and down stairs, peering under beds, opening cupboards sometimes in the same room, and all the time forgetting to find me there.
Perhaps other cats will contribute their suggestions for good hiding places. All of us need them in order to avoid the visit to the veterinary torture chamber.
George
PS Revenge on your human is easier. Withdraw all attention from her - no purring, no looking at her, no rubbing round her legs. Ignore her for at least 24 hours. Refuse to sleep on the bed (unless it is a particularly cold night). This "silent treatment" is hard for a social species like humans to bear. If there is another person in the household, be particularly affectionate to him.
