Necropsy examination of an adult neutered male cat, which was humanely destroyed as it had feline immunodeficiency virus (FIV) infection, demonstrated the presence of a left retrocaval ureter that was entrapped around the left limb of a double caudal vena cava. These associated anomalies originate from the complex embryofetal development of the caudal vena cava. Since no clinical signs had been reported and no gross lesions related to this anomaly were observed, this manifestation should be simply considered as an anatomical variation.
