Well, the best thing to feed lions is a varied diet. The lion will eventually eat, I'm sure but you must try something first. You should get a feeder stich and attach the food to the end to make the food look alive. It seems to work quite well for most people. Move the feeder stick around so that the lion is enticed to follow the food and grab it. You should feed some foods such as, chopped squid, shrimp, krill, silversides, and mussel meat. Try to feed at least 3 of these things to give a good balanced diet.
