I would be very hesitant to bring in a cat or kitten that has never been vaccinated, the stress from the trip itself could overwhelm him leaving him susceptible to illness, and being unprotected makes it even that more dangerous. Same goes with the neuter. If this breeder is a vet tech then she should have no problem giving him an FVRCP before sending him to you, and then I would give him an additional vaccine prior to neutering him.
