Diprosopia in a cat.
A diprosopic cat is described. In the head, two snouts, three eyes and two pinnae were present. The mandible was single and immobile because labial skin of both upper lips and single lower lip was partly fused. Superimposition of upper and lower dental arches was impossible and the mouths remained permanently open. Two incomplete oral cavities were present and the two tongues were joined at their base. The brain was duplicated in part. In the cranium only occipital and temporal bones were normal, the basisphenoid was bifurcated and the remaining bones were duplicated. Embryological mechanisms are discussed.
