The case of a 10-year-old domestic shorthaired cat with severe osteolytic lesions in the proximal femur and the bones of the pelvis is discussed. Bone histopathology showed a malignant bone tumour (osteosarcoma) in the hip joint. A partial hemipelvectomy was undertaken but further histopathology revealed tumour cells in the pubic bone. As further surgery was not an option, the cat was treated with the chemotherapy drug carboplatin, which has fewer side effects than cisplatin. X-rays at 6, 12 and 18 months after amputation showed no tumour growth in the pelvis, although a mass observed near the heart was thought to be unrelated to the previous tumour. The cat has coped well with leg amputation and chemotherapy treatments.
