can help. Last time I took my cats in for their shots , the vet here
told me that they are 3 year vaccines, meaning they are good for 3
years. Then why do I have to get them their shots every year? Is this
true, are there vaccinations that last for 3 years. If so, then why

Vaccinations may very well be good for multiple years in older
ferrets with a good vaccination history - we just don't know. The
approved vaccines for ferrets were only tested on a 1-year basis. To
test for three yeears, you have to take a group of ferrets, maintain
them in a facility for three years - that's expensvie, and for
vaccine companies who don't see anything more than a niche market -
not worth the cost and effort. "If they want to vaccinate ferrets -
they're just going to have to do it every year." (I don't agree with
it - I'm just telling you the prevailing opinion.)

There has been discussion on this list about running titers instead
of vaccinating every year - it's more expensive, less convenient, may
require anesthesia to take the blood, but on the positive side, it
may cut down on the numbers of reactions....
