My last 2 cats were brothers from the same litter that were "dumped" outside at about 8 weeks old by a neighbor in my condo complex while he went on a trip to Europe. One was Creamsicle (pictured in my avatar) and the other Andy, who is all black. Creamsicle passed away 2 years ago from extreme kidney failure, at the age of 10. Andy is still with us.
Despite their rough beginnings, both cats were (are) extremely affectionate with me and my family - but despite the fact that they were litter mates & grew up together, Andy is a definite alpha and desires all the attention, while Creamy was laid back, gentle, and a peacemaker (he would physically get between Andy and any other cat to break up a fight!) Andy would think nothing of chasing Creamy away & tearing out tufts of his fur to make sure he was the center of attention, & Creamy would never retaliate despite his larger size.
I love Andy to death - but I miss my Creamy........
