You are gonna love this!

This thing is SO nice! I hesitated to buy it bcuz it is not metal, but it does have a metal dish that the cat drinks from, and the plastic is BPA free. It is really nice and quiet (almost inaudible), and just the perfect size, smaller than I imagined but holds a bunch of water, definitely at least a weeks worth for one cat, and then I would want to wash it anyway. A real treat to not always have to be washing out the slimy water dish 🤢 Buy it, you'll be glad you did 😉 Oh, and the cat loves it, too! 🐈‍⬛⭐🐈‍⬛⭐🐈‍⬛⭐🐈‍⬛⭐🐈‍⬛⭐
