Hi,
I had the same problem with a female leo that I got from Petsmart. I used reptical, its a reptile version of nutrical. It opens up their appetite, it just takes some effort to force feed them the paste. My female leo eats like a pig (64 grams). If you still haven't found a good home for her I would be willing to take her in.
