Hello I'm sure you'll be overwhelmed with responses to your question regarding the quality of Harlan Teklad Ferret Diet. A quick look at the web site revealed that this food is primarily ground corn and corn gluten meal. Not good! Ferrets require a diet that consists primarily of poultry or other meat products. They get little or no nutritional value from corn products. Furthermore, the diet's fat content (15%) was pretty darn low. I look for foods with at least 18% fat. In sum, I would strongly suggest that you avoid Harlan Teklad Ferret Diet. Some of the better quality foods out there include Totally Ferret, Eight in One Ultimate (not Ultra), Eukanuba Kitten, and Iams Kitten. Happy Ferreting!
