I was getting the one year Purevax because that was all my vet offered. It was getting expensive, so I said I would be moving to another vet.

Lo and behold within 2 weeks I got a phone call that they now offer the 3 year.

At the practice where I go, the owner is a vet, and there are 2 other vets working there. BOTH of the ones working there get the 3 year for their cats! (I was told this in confidence, he hee).

But the new RI law is weird. You get the 3 year vaccine, that is good for one year the first time, even though they were up to date on the Purevax! Then NEXT YEAR, as long as I get them in on or before the one year, they get can have it good for 3 years.
