An 8-year-old spayed female Burmese displayed sudden onset clinical signs of pawing at its face, mildly traumatising its left lip. On oral examination, an SN 208 was found palatal to the normal left maxillary fourth premolar tooth (). The supernumerary tooth was situated in a reverse and mirror position to the normal 208, so that the distal root was positioned mesially, the mesiopalatal root positioned palatodistally and the mesiobuccal root positioned adjacent to the normal 208 distal root. PD3 was diagnosed at 108, 109 and 208, and TR of 309. Closed extraction was performed at 109. The SN 208, as well as 108, 208 and 309, were extracted using the open extraction technique. The SN 208 extraction site was allowed to heal by second intention. The owner stated at the follow-up consultation that the cat did not paw at its face again after the surgery
