There is nothing in the world that's as good as a cat at finding a patch of sunshine. Our cat Molly comes into our kitchen and finds the remaining patch of evening sun and sits in it, no matter how small it dwindles down to.
She is loving that sun warmth. My dog also enjoys the sun coming through the windows. She changes places as it moves... This is a heartwarming shot as your kitty's face has such a sweet smile on it!
