The title is self explanatory. I have a means of gathering animals without wheat via water as the flow is controlled by a push of a button (the beginnings of an auto harvester). I have a glass ceiling only 1 block high (per schema of my place). So once the water fills the room, it will push the animals to one side(no space between the top of the water and the ceiling). This then sparked the question, will they drown before getting to the desired location by flow of the water?
Can they drown at all?
I have seen this post on how to round up animals but it didn't answer my original question.
