African wild dogs
If you thought the orca pod caring for its disabled youngster was fantastic, you're going to love African wild dogs. Once they hunt and kill their prey, bigger stronger members of the pack will step back and let the pups eat first. After the pups are done, the rest of the pack will eat and then venture back to the den to regurgitate some of the kill to feed any young pups, injured or elderly dogs, or just the individuals who stayed back to care for the young ones. In an African wild dog community, everybody is looked after. That's what families are for, after all.
