She looks fat and healthy otherwise, so I'm glad you brought her home
Rescued animals, especially ones who've had less than stellar care (not saying that's what happened to your girl, sometimes stuff just happens) need a home with a person who's dedicated to making them as comfortable and otherwise healthy as possible. Your average owner (aka John Doe off the street) might not have any idea of how to care for a NORMAL leo, let alone one with special needs.
I hope you share lots more pics of her cute little face

She looks super sweet.
