Petmate's Le Bistro Gravity Pet Waterers make life easy for you and refreshing for your pet! Water fills automatically when the level gets low - perfect for keeping your pet hydrated when you're away! (Though you should still have someone check up on them every day!)
Le Bistro is made with MicroBan antimicrobial protection to prevent the growth of stain and odor-causing bacteria, mildew and mold. The diameter of the bottle's opening is 1/2". Please note that the opening is capped and it sits on a smaller opening where the water comes through. It has to be turned to the right to lock it into place.
