I used it, I did trials on it, I don't use it anymore.

On mice, they always had greasy hair and smelled way worse than on rodent diet.
Rats, I did a side by side trial and noticed a very significant drop in production and had more cannibalism as well. Not to mention, they seemed to love the stuff and ate way more of it. I was almost going through two 40lb bags of the stuff compared to one 50lb rodent diet per week. And, the chunks are a tad smaller, so I was getting more wasted food that fell into the tubs. So, I found that between the fact that my number of babies was less, and they ate some of the babies, together with the fact that I was feeding them more of the doggy bag, meant an obvious change back to rodent diet for me. I have also found that my TSC now sells doggy bag for $18 for 40lb bag now, which is more than I pay for 50lb rodent diet....
These are my finding, on my rodents.... Not saying you can't do it, but that's my story.
