In the beginning of 12 Monkeys, Cole's trip to the surface reveals a destroyed city in deep winter. There are no people there, only animals. Among those animals are birds (doves?), an owl, and a bear. Also among those animals are a lion, what seems to be a Madagascar hissing cockroach (whose habitable temperature is 75°F/24°C to 90°F/32°C), and a Nephila spider (a large spider that lives in tropical regions of the world). These are animals that do not live in the snow. Moreover, the lion and the cockroach are not hiding inside, but are out in the open. In fact, the lion is neither hunting nor huddling away from the cold (as a lion should, being an animal with little fat or fur to protect it against the cold), but is roaring on top of a building.
Have the creators ever commented on these hot climate animals appearing to be comfortable in what seems to be deep winter?
Edit: When Cole is accidentally sent back in time to 1990 and locked up in a mental hospital, he finds a similar spider there (and eats it). The hospital is in Baltimore, outside of the habitat range of these spiders.
