(1) A person who finds an estray and who, after giving notice is authorized by the county to maintain and care for the estray, is entitled to compensation from the owner, or from the county, as the case may be, for the reasonable costs of feeding and maintaining the estray; provided, that the county is liable for such cost only if the owner is not located after diligent search.

(2) No person who finds an estray, however, is entitled to reimbursement for feed and maintenance or for any other cost incurred on behalf of the estray before such time as notice of the estray is given to the county or to the appropriate animal control office.
