I feed live. I do have one pastel female that was refusing. After 3 months of not eating, I filled the tub with wadded up newspaper put in a fresh killed rat. It was gone in the morning. That was last Sunday. I fed her again last night same thing, P/K...checked this morning....rat was gone.
She has always been a picky feeder. I have had her for a little over a year and she has not gained much weight. Now hopefully I have discovered a way to get her to eat on a regular basis.
I have two normal girls I got from TSK. They were mouse eaters. I had no problem getting them to accept rats.
I started with weanlings, then worked them up to a proper sized rat a little at a time.
