Hi. Just want to tell you about my experience. I went away a few weeks ago for 3 days and left my husband in charge of my piggies. I have 2 water bottles on their 2x4 cage. One on the bottom, and one on 2nd level. I showed my husband how to fill up their water bottle if it should become empty. My husband is not to swift when it comes to changing light bulbs, water bottles, etc.
When I came home my husband casually mentioned to me that they didn't drink much water and isn't that unusual. It is very unusual because they are big water drinkers. They very rarely drink from the 1st level bottle, usually its always the 2nd level they prefer. After monitoring them the next day I noticed that they in deed were not coming up stairs to drink from their favorite bottle. Upon inspecting the bottle I noticed that hardly any water was coming out from it. Upon closer inspection, I realized that the bottle cap was closed to tight and I guess by tightening the cap too tight it didn't allow for water flow. Good thing for the 2nd water bottle.
So the lesson here is I would definately have an extra water bottle hooked up to your cage just in case one is not working.
