The botanical gardens in Buenos Aires - Jardin Botanico - is a beautiful place, and completely filled with stray cats. You can take a seat on any bench, and within a few minutes you'll likely be joined by a cat (or six), and see local residents coming in with food to spend some time with them.
Not all the strays are friendly, however, and I spotted this one who had found a quiet spot behind one of the buildings. The late afternoon shadows hit perfectly, and I couldn't resist taking the shot (one click, however, and she threw me some evil eye and slinked away).
