Prior to the weather changing, I step up feedings. I feed every 5 or so days then might throw in an extra feeding every couple of weeks. If they (the females esp.) want it I will feed them on that schedule. Once the weather cools, which in Az. could be into Nov-Dec (nights into the 60's) I start to slow the feedings. Maybe every 7-10 days. I want the seasons breeders to be able to digest their food without complications. When it starts to warm up again, I increase my feedings, especially for the females. I rarely feed anything bigger than a small anymore, unless the rat just gets bigger while I have it.
