you "CAN" but it is not recommended. Ball Pythons tend to stress easily, and having 2 together could cause stress. That being said, if you had a large enclosure for them, I see no issues at all with keeping them together. As far as feeding them, I would feed them separately. Take one out to handle while you feed the other, then a few days later do the same but with the other snake. Stagger their feeding schedule. Alternatively, you could feed them on the same day, in a "feeding tub" so that they are separated. Don't feed them together.
