I have 2 girls eat right up to ovulation, the rest tend to go off feed about a month before ovulation or right around the time of the pre ov shed. Any girls that go off for too long I will offer live mice to, even the girls off feed can't resist a mouse normally. I normally feed rats with ASF's filling in on the smaller snakes or the ones that won't eat F/T if I am out of appropriate sized live rats. So on the rare occasion they get mice, they almost always take advantage of it.
