My husband's dad used to feed Sprout to his Britts years ago, they were itchy all the time, and had white scales on their skin, but they felt really oily. Yuck. They switched to a higher quality food, and wa-la, nice coats, 1/2 the poop, and the Britts weren't greasers. I don't think the quality of the ingredients is too good. Listen to your wife,
stick with the Black Gold.
