If a law enforcement officer authorizes removal of an animal pursuant to chapter 16.52 RCW, the person or entity receiving the animal and aiding in its care or restoration to health shall have a lien upon the animal for the cost of feeding, pasturing, and caring otherwise for the animal. The lien attaches on the date such costs are due and payable but are unpaid. Any such person is authorized to retain possession of the animal until such costs are paid or the lien expires, whichever first occurs.
