I love this food. I know I was going through a 50 pound bag of PMI in at least a month with 20-30 rats. It takes me a month and a half to two months to go through the same amount of Harlan Teklad with the same number of rats. I have also noticed that the rats are more svelte now and not as chubby. I would dare to say some of mine were bordering on fat, but aren't as bad now as they were.
Shipping is also excellent.
I generally get it within a week of placing the order, but usually sooner.
