She seems to be doing an excellent job with this gift of hers, where she saves the lives of countless animals. Theres only one catch to her gift - she cant tell anybody about it, otherwise she would lose this unique gift.
In the movie The Wild Thornberrys, she is forced to tell her secret, whereupon she lost her gift. This was quite unnerving for Eliza, even more for her pet baboon, Darwin. But luckily the Shaman gave her gift back, since the tattle-tale wasnt hers to control.
