Must have been 10 years ago there were some posts on the net about Black Diamond having 2 issues. Both of them connected with the production of the stuff which results in bags with varying composition:
1. Sharp edges of the particles.
Cories cut their whiskers on them.
2. Toxic ingredients whose toxicity varies depending on the source of the material.
But these were old posts, 10 years ago. I'm sure now things are clean, organic and always low-fat
