Yeah, they're all brothers. They still wrestle with each other, but they're great. We introduced 2 other foster kittens to them and they welcomed them in with no issues.

Jojo is the mom of all three. We were just going to get Jojo as a pregnant foster mom, then Meatball got on her cage and they asked if we'd take him. He was the only surviving cat from her first litter in the colony. We ended up quickly foster failing him. Then Jojo had her 5 kittens, we foster failed Marty and Emmett and adopted out the other 3.
