I am curious, I know parents aren't supposed to play favorites, but we all know that if asked most will say they have a favorite child or child that was much easier to raise. As pet parents we are no different, we have to raise, train, and discipline our "kids."
I will be the first to admit I have a favorite, BUT only because she is 3 years older than the rest and we have a special bond due to personal hardships we have survived together; my favorite is Kotton. I do try not to treat her any different but I know she gets more attention and more or prime "mommy real estate" on the lap (even though she is the smallest). As far as non-furry favorites I would say Scar, also because we bonded over our similarities (we both have a bum left leg and a weak right).
