Summary

A diagnosis of congenital bilateral patellar aplasia was made in two male littermate Siamese cats that presented for abnormal conformation and hind limb gait. Both cats had abnormalities of the femora, tibiae, fibulae, and tali. The owners reported that the cats were able to ambulate adequately in the house and jump onto low-lying objects. Other than signs related to this developmental anomaly, significant abnormal clinical signs were not noted in either cat. According to the owner, none of the other littermates were affected, but the seven year old sire displayed identical clinical signs. Unfortunately, the sire and littermates were not available for examination. Treatment was not pursued for either cat.
