Yes, from what I understand obesity leads to diabetes in cats.
Obesity is not a light-weight matter 8-O, it's just not the kind
of thing I am looking for.

You've got a conclusion and are looking for supporting evidence. Not
a good research discipline.

You're right, I should rephrase. Steve says:

Hill's has a tradition and history of treating disease with the
Prescription Diet products. As a consequence the level so fnutrients
like calcium and phosphorus that are so critical in renal failrue and
other diseases get particular attention. As a consequence dietary
development is always looking at the disease we see and trying to
avoid them. 50 years ago we saw pets in veterinary clinics with
examples of deficiencies in the diets, today we see only the results
of excesses in the veterinary clinic.

Ie, Hill's Science Diet is formulated to prevent nutritional excess.
This is apparently a strong motivator for Hill's R & D for the pet
market, and it's been repeated by folks such as Phil and Chris who
believe strongly that Hill's research represents the pinnacle of dietary
development.

I ask Steve what an example of disease caused by nutritional excess is,
because "dietary development is always looking at the disease we see and
trying to avoid them [sic]".

I am not expecting an answer that "obesity is a problem caused by
nutritional excess" because then Hill's would be developing and
marketing an educational campaign to get people to feed their cats less
food--including Hill's food, of course.
