Thanks. I have heard that males typically will go off of feed in the winter but I didn't know females did the same. The one that has been off of feed since Dec is my 700g butter male. And then I have a 680g female normal and a 800g female Mojave that have been off of feed since late Jan. I have been weighing them every other week and haven't seen a major weight change, although they have lost a little. But I guess that is to be expected.
