You know how the more you love someone, the most names you have for them?
First he was #3. Since he's the most clingy/fraidy/whimpery, he became #3 Poor Me. (More on personality in a moment.)
Our family was visiting when he pooped a nice large pile, so they called him "Sir Poops a Lot" which became "Sir Cries a Lot" since that's what consistently stands out about him. Then just "Sir Max a Lot" because we had a beloved dog Max who also made his needs known vocally.
Somehow...because we love Parks and Rec and their ongoing fondness for the miniature horse Lil Sebastian - who has similar color and proportions to #3, we're now calling him Lil Sebastian.
Maybe we should call him "Mini Mabel" since he looks nearly exactly like his mom. He's got her copper-brown color and even the white stripe up his nose. Now Mabel also has a diamond on her head - but #3 is still a stunner, with white toes like Mabel.
Though he's a whiner, we think it's just that he's more human-oriented than his siblings, and will prefer a household with plenty of human attention. He's easy-going and playful with Mabel, siblings and us, and the most likely to look for laptime, then snuggle in for a nap.
