We have an American Toad as a pet that we found in our yard in July. He is in a 10 gal tank with coconut fiber substrate. He has dechlorinated water in his little pool and a log to burrow under and a clay pot with entrance. He seemed perfect until six days ago. He stopped eating and now will not come out of this clay pot/burrow. He has no interest in food. His diet before that consisted of mealworms and crickets all from the pet store. He seems otherwise healthy but he just won't come out to eat anything. The crickets even sit right in front of him and he doesn't even care. I am considering letting him go but my son (6 year old) doesn't agree!!! Any suggestions? Is this normal? Hibernation? Indoor temp ranges from 69-74. I do not have a light on him.
