Feline Developmental Bone Disorders

1,664 words 7 min read 1 figure Reviewed November 13, 2026

Developmental bone disorders are diseases of the growing skeleton. The best-known ones, panosteitis and hypertrophic osteodystrophy, belong to dogs. Cats have their own, smaller list: an inherited cartilage and bone disease of Scottish Fold cats, bone disease from unbalanced diets, and a few rare syndromes. This guide separates what is canine from what is feline.

Key facts

Developmental bone disorders (panosteitis, hypertrophic osteodystrophy) at a glance
  • Species and system: kittens and young cats; musculoskeletal.
  • Canine diseases, not feline: panosteitis (feline cases are anecdotal only) and hypertrophic osteodystrophy (young, growing large and giant breed dogs).
  • Feline conditions: Scottish Fold osteochondrodysplasia (TRPV4 variant), nutritional secondary hyperparathyroidism (all-meat diets), hypervitaminosis A (liver diets), and rare ones such as multiple cartilaginous exostoses and patellar fracture and dental anomaly syndrome.
  • Diagnosis: signalment, diet history, radiographs; targeted blood tests.
  • Treatment: mostly dietary correction and pain control; there is no cure for the genetic disease.
