No American Toads need hibernation to breed. You would have to put them through a temperature change and it's a long process it's not a process you can skip anything or the toads will die. All American and Fowler's need to hibernate. You can just get noises on YouTube and play them on a TV or phone or something for hours so they can hear them. If you are you planning on hibernation?
