CA Civ Proc Code Section 1208.5

Any person having a lien upon any animal or animals under the provisions of Section 597a or 597f of the Penal Code may satisfy the lien as follows: If the lien is not discharged and satisfied, by the person responsible, within three days after the obligation becomes due, then the person holding the lien may resort to the proper court to satisfy the claim; or may, three days after the charges against the property become due, sell the property, or an undivided fraction thereof as may become necessary, to defray the amount due and costs of sale, by giving three days’ notice of the sale by advertising in some newspaper published in the county, or city and county, in which the lien has attached to the property; or, if there is no newspaper published in the county, then by posting notices of the sale in three of the most public places in the town or county for three days previous to the sale. The notices shall contain an accurate description of the property to be sold, together with the terms of sale, which must be for cash, payable on the consummation of the sale. The proceeds of the sale shall be applied to the discharge of the lien and the costs of sale; the remainder, if any, shall be paid over to the owner, if known, and if not known shall be paid into the treasury of the humane society of the county, or city and county, wherein the sale takes place; if no humane society exists in the county, then the remainder shall be paid into the county treasury.
