Gosh...catching up here--been doing yard/pond work for a few days. I did call Purina (and I'm in Richmond, IN area) and I was told the same names of the same places I'd already called. The lady on the phone said call these places back that it could be 'special ordered'---right. I too had talked to a frustrated TSC guy who cannot get the stuff. So, I'm sticking to other brands and may even try some of what y'all are talking about further up if it's in my area. So sad, to advertise something that isn't available to many of us.
On a flip note, I still have my automatic feeder going, the fish aren't eating as much until late evening, they're bedding now. My fish feeders run on batteries and the batteries last a long time.
