Since I've just gained so many new rabbits, I wanted to make my job easier. On Saturday, I decided that my water bottles were too time consuming to fill and that I should cut the tops off of them so that I could just fill without pulling each one down. :roll: DON'T DO THIS. Apparently, you need the pressure in the bottle to keep the water from pouring from the drinker valve. I had to scrounge for old water and soda bottles (12 of them). Because the soda and water bottles are soooo much smaller than my other bottles, I must fill much more often until I get my replacements next week. This...not such a time saver. Live and learn, but NEVER cut the tops off your water bottles with drinker valves w/ the balls. :evil:
