You can try offering live if that is the route you want to go. I have a male normal that used to eat f/t but then just stopped eating all together. I had to put him back on live to get him to eat again. He absolutely will not eat f/t anymore. I even tried the tough love approach, but he went 43 days without eating for me, and then I broke down and put him back on live. He has been eating very well ever since.
