Sorry for butting in here, I know this post was for Kathryn.
There actually is a lot of discussion going on even among vets (even some non-naturopathic vets) if the yearly booster shots don't do more harm than good and the question is if they are really necessary.
My college roommate is a naturopathic veterinarian and she advises to do the initial series in cats and dogs which should be done within 18 months or 24 months. I was told that the yearly booster shots are completely unnecessary (it kind of makes sense to me, we don't give our kids booster shots every year, do we?)I also had seen quite a few adverse reactions in my pets after the yearly shots.
After talking to my friend, I also read several books about this subject, in my opinion the best one was Dr. Richard Pitcairn's "The Complete Guide to Natural Health for Cats and Dogs".
I still have my pets vaccinated against rabies since it is the law. But I stopped all other vaccinating with my two older dogs (8 and 10 years) when they were around 5 or 6 years (based on the info that I had and the research I have done on this). The puppy does his regular "puppy schedule" in vaccines right now.
Some people may find this wrong, but this is a decision we as a family made based on the information we gathered (and no, it was not money or budget-related) Other families may come to a different conclusion and do the yearly booster shots, and that is ok, too!
As to the breeder, I actually applaud her for taking a stand if this is his/her conviction. To me it shows, that she cares about the animals he/she puts into new homes and isn't just out to sell them quick to whoever comes up with the $$. Not everyone may agree with her convictions and I am sure she will be running a risk of loosing some potential pet owners.
I guess it is a free market, if you are uncomfortable with not vaccinating a cat, don't get a cat from that breeder. If I wasn't convinced one way or another, I wouldn't let myself get locked into a contract that I am not sure I can or want to adhere to.
So, whatever you do, good luck with your new kitten. Keep us posted about your new family member!
