> Rattling off statistics that she has internalized as a volunteer, Ms. Adams points out that eight out of 10 street kittens die within their first six months. Those that survive are often disease-ridden. Winters here can be deadly for a species that originated in the Mediterranean climate of North Africa. And traffic takes a big toll.

I wonder if those kitties show genetical adaptions specific to their challenging environment? Is their population and breeding speed enough to allow for useful (micro) mutations to appear?
