Thanks everyone. I will email them again and ask them if they are breeders.
I am very close to San Mateo and also not too far from
Cavy House. I've been there, great facility. The thing is, I wasn't actively looking for a pig to adopt. I already have 3 lovely boars (who live together peacefully *knocks on wood*). I just happen to come across this ad and thought I have room for one more. If they are not breeders, and if he can't find a home after a week, I might get him.
