As I am testing my rack and Helix, I keep thinking of more questions. Should water bowls be filled with warm, luke-warm, cool or cold water. Most pets should be given cold water, but I give luke-warm water to my birds since they come from a warm tropical environment and I doubt they have access to much cold water. I would think BP's only ever have access to warm water, too, so don't want to offer cold water if it could possibly lead to illness. So what temp water do you use for your BP's? Thanks in advance.
