It's clearly a toad. The only toad that occurrs in the Des Moines area is the American toad. Feed it lots of tiny invertebrates- I would suggest culturing fruit flies and bean beetles ASAP. They have big appetites at this stage.
okay. ive thought about that actually but i wasnt sure toads could climb so much. i bought a culture jar of fruit flies a few days ago and i got them a 20 gallon aquarium which is about 60% land.
100% land, with a shallow water dish, would be better. They don't mind humidity, but should not be kept wet.
Little toads can climb low shrubbery and branches quite well.
