Plain-English summary
A 1-year-old female cat was brought in because she was losing hair, having trouble walking, and seemed stiff. X-rays showed unusual hard lumps in her neck, back, shoulders, and legs. After further imaging, the vet diagnosed her with fibrodysplasia ossificans progressiva, a rare condition where soft tissues turn into bone. Unfortunately, this condition is not well understood and can lead to serious mobility issues.

Abstract
A 1-year-old female cat was presented for progressive alopecia, gait abnormalities, and stiffness. Radiography demonstrated multiple calcified lesions within the soft tissues of the cervical and thoracic spine, shoulder, and limbs. Postmortem computed tomography provided more detailed information on the distribution, pattern, and extension of lesions. In addition, computed tomography helped guide sample selection for histopathology. The final diagnosis was fibrodysplasia ossificans progressiva. This is a rare disorder of unknown etiology, characterized by fibrosis and heterotopic bone formation in connective tissues. To the authors' knowledge, this is the first report describing this disease in a European cat.
