Whenever complaint is made on oath to any magistrate authorized to issue warrants in criminal cases, that the complainant believes and has reasonable cause to believe that the laws in relation to cruelty to animals have been or are being violated in any building or place, the magistrate, if satisfied that there is reasonable cause for that belief, shall issue a search warrant, authorizing any officer, competent to serve a warrant, to search the building or place; but no search shall be made after sunset, unless specially authorized by the magistrate upon satisfactory cause shown.
