There’s a big black guinea pig named King Kong, butterflies and snakes, turtles and fish, a handful of curious rats and a bird named Steve. They’ve all found a home at the Palouse Discovery Science Center in Pullman, some from rescue and one simply by showing up. “I got home one day, and I heard this twittering up in one of my trees,” Victoria Scalise, the center’s executive director, said of the day she met Steve. “And I looked up, and there he was. My son was going to climb up and get him, but when I held out my finger he simply landed on it and that was that.”
