No, it's harmful to its health. Juice doesn't matter much (but you can only drink a small amount of juice).

Don't let it drink too exciting drinks. It might make it uncomfortable. It won't think of anything else. It only thinks: I want to eat, I want to eat.

Pay attention when the owner leans against it. Don't make it too full ... you'll get sick ... ~O(∩_∩)O~
