The frequency and the morphology of the abductor cruris caudalis muscle were studied in 58 adult unknown breed cats. The sample included 36 females and 22 males. After the dissection, were found a frequency for the presence of the same muscle of 98.3%. The abductor cruris caudalis muscle appears symmetrically in 35 females (97.2%) and 22 males (100.0%). When present, it were originated on the transversal process of the 1st vertebrae caudales, in the glutea region, below the gluteus superficialis muscle, throughing almost all the thigh under biceps femoris muscle, where it make a parallel relation with the sciatic nerve, receiving nervous ramifications of the same in 78.3% of the cases. The medium found for the width and thickness of his muscle venter was respectively of 2.03 mm and 0.35 mm. Its insertion occurs on the biceps femoris muscles approximate to the fascia cruris, where both finish fusing theirselves.
