More Ultravision!

Turns out, birds and fish aren't alone.  Cats, dogs, and several other mammals can also see UV light:

Douglas, a professor of biology at City University London specializing in the visual system, and co-author Glen Jeffery, a professor of neuroscience at University College London, determined that cats, dogs, rodents, hedgehogs, bats, ferrets and okapis all detect substantial levels of UV.

So, I've added the Ultravision Species Trait to the Featured Creature entries for small cats, dogs, and squirrels.

When I get around to them, it'll also belong to the rest of the rodents, to reindeer, bats, etc., as well as most of the birds and fish.

If you're one of the handful of people who've downloaded the Quick Start Rules, make sure you include this awesome old-school ability for your cat, dog, and squirrel characters.
