Abstract

An 11-year-old castrated male Maine Coon was referred to the Animal Medical Center with a history of no tail carriage. The cat had a loss of perception in the distal part of the tail. Imaging revealed an extradural lesion on the ventral aspect of the L6‐7 region. A L6‐7 hemilaminectomy was performed on the right side. Extruded disk material and conus medullaris were observed in this area. The cat displayed a slight improvement in tail movement, but did not recover perception of the tail. In this case, the conus medullaris was located more cranially than usual, in which the spinal cord ends at the L7 or the sacral vertebrae. Therefore, the neurological signals were limited to the tail. There may be individual differences in the location of conus medullaris in cats.
