Simba's growing up quick. At 4 months, he's already 40 pounds, quadrupling his weight since we brought him home two months ago. I think he's probably got about 50 or 60 more pounds of growing left to do. Here they are in a rare moment where one of them isn't pouncing on the other and wrestling. That's Simba on the left, and big sister Nala on the right.
