While multiple cats may have no problem sharing a dish that is kept full at all times, sharing a bowl on an automatic feeder can be problematic. Since only a certain amount of food is provided at each meal, one cat may end up eating all the food while the other cats end up not getting any. Not all cats will be as motivated to eat as soon as the food drops out of the feeder, so slower cats may miss meals if a quicker cat gets to the bowl first. If your cats have feeding habits that aren't conducive to sharing a bowl, consider a separate feeder for each cat. There are also feeders that dispense food into two separate bowls, including one recommended in this roundup.
