HIP-DYSPLASIA IN A LITTER OF DOMESTIC SHORTHAIR CATS

A 14-month-old female Domestic Shorthair cat was presented with bilate rally shallow acetabuli, flattened femoral heads, and subluxation of t he hips, changes consistent with hip dysplasia. Follow-up radiographs showed additional osteophyte formation and remodeling of both coxofemo ral joints. Two of her female littermate exhibited the same condition. Pelvic examinations of a male from the same litter as well as those o f the queen and two other 3-year-old offspring were normal. This repor t demonstrates that it is likely that genetics plays a role in feline hip dysplasia, although further detailed reports and similar investiga tions of related cats affected by this condition are needed.
