Persons residing in the unincorporated area of Pierce County may keep potentially dangerous wild animals other than those defined in and prohibited by RCW 16.30.010 if they obtain a permit as defined in PCC 6.07.040 from the Auditor or the Auditor’s designated agent. Such permits may be granted only upon a showing by the applicant that adequate safeguards have been instituted and will be maintained which effectively control any dangerous or vicious propensities of such animal, and eliminate any danger to individuals and property, and that the keeping and maintaining of such animal will be in the best interests of the animal and will in no way constitute a nuisance to the occupant of any surrounding property. It shall be the duty of the animal owner to comply with this Section and to maintain proper supervision and control over his or her animals at all times. When a potentially dangerous wild animal causes injury or damage, the responsibility shall be upon the animal owner and not the County.
