Website on ingredients in different brands?

A while back ago I remember seeing a website that broke down  ingredients  of cat food brands so you could compare and contrast.  I know this website listed which brands used by-products vs. human grade meat exc...but I can't find it.    Does anyone know of any site that may have this information?  Thanks

Maybe this one? The info there is from 2011 so it's not very reliable.

This old thread may be of some help: http://www.thecatsite.com/t/245771/wet-food-ingredient-comparisons
