Hi all, I didn't respond to this at first 'cause I have just started using this about a month ago. I was using Sheppard's and Greene which cost 17.99 for 5 pounds. In Spokane, Washington, I can get a 25 pound bag of Mazuri for around 25.00. Since I have 4 of my own furchildren, and will soon be fostering others, I need to buy GOOD food for as inexpensive as possible. As I compared the two across, (My thanks to Tracy at Ferret Rescue of Spokane for suggesting this) I found that Mazuri was not only compareable, but far better in most aspects than the Sheppard and Greene. As I said, I have only been using this for about a month, but I have already seen an increase in energy, (as if they needed it <sigh>) and a healthier coat on all four of my babies. One I had to switch over gradually, and that took awhile, but the others had no problem. I would be interested in any information regarding this too. I can share what I have seen, but would also love to here from others. CJ with KoKo, Kapu, Sugar and Bearatito Sweets to the Sweet Rabbitry and The Zoo Crew [Posted in FML issue 2559]
