Yes I do! A fantastic one actually! Quite possibly the best rabbit vet there is. Her name is dr. Harvey and she is at the Chabot veterinary clinic in Hayward. I drive quite a ways to her, past multiple other rabbit vets just to see her. It may be far for you, but I guarantee shes worth it. She's also fairly inexpensive, so an added bonus. Lots of reviews online about her as well you can look up.
We used to live in Tracy and our Vet was in Oakley, but Santa Cruz is a far piece from there or the bay area--Monterey may be a better area to check on.
I don't know any in Santa Cruz mtns, but am familiar with the area. If nothing in Scotts Valley, check Los Gatos and Saratoga.. IME, people are VERY pet-centric in those towns.
My brother's in Merced, so kind of near Fresno. But he has no bunny. lol
I, on the other hand, live near Los Angeles.
Marshi, there's a rabbit rescue that sells hay/bedding/treats/chews/etc. in Van Nuys (Bunny Luv), as well as one in Monrovia (Bunny Bunch Boutique). Both have good supplies for rabbits.
