Royal Canin studies new strategies for obese cats

A randomised, single-blinded, positively controlled, field trial for weight loss in obese client-owned cats was undertaken to look at novel diets and dietary strategies that could improve owner compliance and, therefore, success of feline weight loss programmes.

Three dietary strategies were evaluated: strategy A used a novel dry high fibre ration; strategy B used ready-prepared portions of dry and moist food; strategy C used an existing commercial dry high fibre ration fed with a measuring cup. Cats were assessed at weeks 4, 12 and 20, and adjustments to the energy allocation made if required.

Mean weight loss at 20 weeks (A: 11.0+/-1.3%, B: 10.9+/-1.2%, C: 11.9+/-1.7%) and mean energy allocation (A: 31.0, B: 28.5 and C: 32.2kcal/kg of target body weight/day) were similar amongst strategies. However, owners’ subjective hunger score was significantly (P<0.001) higher with strategy C than with strategies A and B. Further, owner satisfaction was lowest with strategy C, and more owners also regarded food allowance as insufficient with this strategy.
