Recently, though, we've added Scarlett (name for now). S/he's a crested gecko. Crested geckos are different from leopards not just by coloring, but by being more arboreal. Her cage has more vines/logs/sticks to climb as they spend more time off the ground than on it. She also eats what's called 'crested gecko food'. Very simple, add water, mix, serve. She's only about 3 months old, so she's VERY small.
At some point in the future, my daughter wants to add her own gecko. We're watching to see if perhaps we can find a panther gecko. She hasn't totally decide which variety she wants, though.
