I have so many photos that would fit this category, that it's really hard to choose. The one I'm submitting pictures three (out of four) generations of a cat colony we rescued earlier this year. All the cats you see on the photo were feral at the time and each and every one has been domesticated I took this photo at the early stage of befriending this bunch.
The one in the background (Fluff) is the mother of the two youngsters in the middle (Portos and d'Artagnan ... although on the daily basis we call him Umpa Lumpa, but that's a different story). The one to the the left (Aramis) and the one to the right (Amber) are two brothers that are either younger siblings or cousins of Fluff.
Amber was the most aloof cat out of the whole colony. Under the roof he became the biggest fan of belly rubs I've ever known.
