Title: Cat diet research
Post by: Spartycats on February 25, 2011, 06:14:00 AM
This study was funded by Waltham (part of Mars Petcare).  I thought it was very interesting (what I could understand of it).

Geometric analysis of macronutrient selection in the adult domestic cat, Felis catus

From within:
We estimate from the data ...that the intake target lies close to 26 g day–protein, 9 g day–fat and 8 g day– carbohydrate, yielding a macronutrient energy composition of 52% protein, 36% fat and 12% carbohydrate. (

That looks like a good article!  Maybe it will help get home made diet prep closer to the ideal.  If I could only figure out the Alnutrin calculator!

I love the statement that the studies were designed to "disentangle the complex interactions among dietary protein, fat and carbohydrates".  Achieving the optimal cat diet without going to whole prey feeding does seem like a messy business.

That was a very impressive experiment and confirms the thoughts of pretty much all of the people on this board that the composition of cat food should be highest in protein, lower in fat and lowest in carbs. It's pretty funny that they found the ratios: 56% PRO, 36% FAT and 12% CHO for macronutrients based on energy requirements. I wonder if Mars will now heed their own research and change the formulations for many of their products to reflect the CHO ceiling they described. Essentially, 17 g/day of carbohydrate is the most any of these cats required when self-regulating. This also shows that our theories of a varied diet is valid -- even in terms of what they require to make up macronutrients that are not available in one diet (can be made up with another food on another day). Bottom line on this one is high protein, very low carb.

So, is this going to change anything for PFCs? Some are already formulating dry foods this way (Orijen, Innova, Petcurean, and others) with their grain-free, high protein diets. I'm glad they've done this study. Now, if only they will read their own results!

I also hope they follow up with their other proposals to evaluate what role texture, smell and water content has in cats selecting one food over another.
