I agree with everything Calparsoni wrote...the heat may have been too much for it. Also the fact that it may have been a weak baby to begin with, genetically. When temps. are extreme, you can still get them outside for a half hour or so in the early part of the day before it heats up, that way they still get natural light, which is the best. Hope you get another one and enjoy, because they are delightful and relatively easy to care for.
