Someone who loves animals (in a nice way).
Opposite to Faunacator (who loves animals in the naughty way.)
1. Sally was a fauna fan who worked at a zoo and spent her spare time fundraising for wild animals. Jim was a fauna fan too, but he lived on the moon, so his menagerie consisted of two robotic goldfish and a wall full of animal posters.
2. I'd rather be a fauna fan than a fauna-cator.
