Cal. Bus. & Prof. Code § 4826.2
Notwithstanding any other provision of law, a veterinarian, registered veterinary technician, or a veterinary assistant working under the supervision of a veterinarian, may provide veterinary care and treatment for any animal restricted pursuant to Section 2118 of the Fish and Game Code. A veterinarian, registered veterinary technician, or a veterinary assistant working under the supervision of a veterinarian, may lawfully possess one or more of the animals only for the period of time that, in his or her judgment, veterinary care and treatment are necessary. No veterinarian, registered veterinary technician, or veterinary assistant working under the supervision of a veterinarian, has a duty to advise law enforcement if he or she becomes aware that one or more of the animals is possessed in the state. For the purposes of this section, "veterinary care and treatment" does not include boarding when no veterinary care or treatment is required.
