Hello - I suspect that the concern would be the higher protein levels of insect diets, because excess protein is broken down into ammonia, which has to be processed by the kidneys and can damage them on the way out. This is the reason that most commercial renal diets take care to keep protein levels relatively low, although it has to be balanced against the need to maintain and ideally to build muscle. To my understanding, the companies try to counter this with their choice of proteins. The main reason that cats lose muscle mass in these cases might not be nutritional scarcity of protein, but dehydration, sickness and lack of movement - however, this is worth checking for your individual cat with your vet. The really cool thing about prescription diets is that they are generally attached to a customer service system and your vets can call their vets with any questions about the nutritional information that may be outstanding, so it's worth getting in touch.
