yes they work but why wast your money on them when you can make your own out of a 2 litter bottle.do they work, is anyone using them and if so let me know wat u think. I saw some at wal-mart and my granny uses some in her house plants and they do fine. Will They Work?????????????????????
that wont work cuz the rabbit pushes that little bearing up iso the water comes out. you just need a really small hole in the cap so that it drips.well i heard something about using a rabbit feeder nozel and a two liter bottle but it sounded a little sketchy
