I fed my newbies last night. I have 3 total, 2 of them have taken F/T and the other has been very picky. I ended up giving her a small mouse to boost her appetite 10 days after I got her. Tonight I had a live mouse in the room a few hours before feeding. Offered her the F/T, got her interest but she wouldn't strike. Put the pup back on the heating pad and tried offer to my other boy with the same response.
Ended up putting it back on the heating pad and waited a couple minutes. Tried offering her the pup again, but when she seemed really interested i immediately switched out for the other pup and she struck a couple seconds later. I think the issue is they take their time investigating and by the time they are ready the pup is too cold.
