Until just now... :52: I had never tried ANY pet foods.
When I was a teen and younger adult, you hear of your friends trying dog food, but as curious as I was, I just couldn't do it. Yuck.
I just popped in my mouth a small handful of both Harrision's regular, and the high potency formula. I admit that just the though of trying it grossed me out, but I did it anyway. They tasted the same... Sort of like tasteless cereal. Grain-like taste.
My birds LOVE that stuff like it's candy. They say birds don't have a very highly developed sense of taste. Apparently not!
