S.C. Code Ann. § 58-13-630: Livestock.

In case such refused or unclaimed freight is livestock, then, in order to protect the interests of all concerned, it may be sold after ten days' notice in writing to the consignor and the consignee, when known, by United States mail or otherwise. The proceeds of such sale shall be applied to the charges of transportation and demurrage and to the expenses incurred in caring for such livestock and all other lawful charges assessed against them, as well as any legitimate expense connected with the sale thereof, and the balance shall be accounted for to the rightful owner upon satisfactory proof of ownership.
