Missouri Revised Statutes Title XVII. Agriculture and Animals § 271.040. Any householder may take up stray, when

If any horse, mule or ass, liable to be taken up, be found on any plantation, and the occupant thereof refuse to take up the same, any householder of the county may give said occupant five days' notice, in writing of his intention to take up the said stray, and at the end of five days from the time of giving notice, may take up said animal and proceed in the same manner as if it had been found on his own plantation, except that in filing the affidavit required in section 271.060, he may omit to state that the same was taken up on his plantation, but in lieu thereof shall state the name of the occupant of the plantation on which the same was found, and also that he gave said occupant five days' notice before taking up.
