What part of AZ did you visit? We are up near Prescott and have only seen the one toad this year. I used to see more during the rainy season but we had a really cold winter last year with lots of snow so not sure if that affected them or maybe predators are getting them. Do you know what the life span is on the native toads? My son is really hyper sensitive about things dying so I want something that hopefully will have a decent life span so he will be older before we have to deal with it. Also, what size container would I need, I have one terrarium, which is the more upright kind. I'll check and see if I can find anyone local or even down in the Phoenix area who might be selling frogs or toads, probably cheaper to make the trip to pick them up than pay the shipping.
