I didn't use the CA vet, I was in NC. However, I brought:
- completed EC998 (filled out with all the info about the pets and microchips/vaccination/bloodwork)
- rabies certificates with microchip numbers on them
- FAVN form from Kansas showing bloodwork result
- receipts from vet showing the dates of microchipping/vaccination
As it turns out, they only needed/looked at the EC998 form, but they advised me to bring everything in case they had any questions.
I went in person to their office, because I wanted an instant result and to avoid the angst of possible postage issues. If I were mailing it, I'd probably get a pre-paid envelope (with tracking number) to give to them so that I could know when they'd be sending things back (and where they were).
Good luck!
