I actually mix a little of it in with Arnie and Kira's pellets (one part readigrass, one part SS mature and six parts SS normal).
They love it but I mainly put it in there to make Arnie put on weight again, which it has done. Their poops are fine but Kira's getting a little chubby :lol:
I've been making that mix up for about 6 months now.
