Those kittens were hungry and I managed to lure them nearer (I had an FM2 and the 180mm with a 100 ISO film at almost noon under the pine trees...) The female (forefront), taking risks, while the male one was much harder to get closer till he assumed a protecting position on his sibling.
While they look just like ordinary kittens, they grow with bigger ears, whiskers, and "fatter" cheeks and keep the distinctive stripes. They are crossed between an authentic wild species (that has disappeared)and the common straycat.
