I tried rescuing another leo a week or so ago, there's a thread about it somewhere. Turns out they just gave her back to the breeder.
Make sure it's getting the calcium supplement. You can keep a dish of mealworms in the cage at all times. Just try and rotate them, I rotate mine every day. I also offer crickets once in the afternoon. Three mealworms a day doesn't sound like enough, unless we're talking a little baby. Does it still have the oblong color patterns/bands or have they turned into spots already?
Get some pics up!
