Well, if u REALLY like lions, then I would get another lion! Just next time, buy a bigger one so he will live longer if he doesnt eat right off the bat, make sure he is eating frozen, watch him eat, ask how long he's been there, etc! BAM! You got a healthy lion! Also, lions are VERY susceptible to ammonia poisoning. I know he isnt eating, but that could be adding to the problem. Spinning around in circles like you said in your other thread sounds to me like ammonia poisoning. What are your water params?
