Weight loss is more common in kidney patients but i would be concerned she may be retaining fluid causing bloating or swelling. Please have her rechecked by your vet, they can advise on amount to be fed also, excessive diet restriction can prevent weight loss also as the body trys to retain as much nutrition as possible
