We just love the Big Wave Dog bowls Have used them every day since we got them. Just fill them very day with fresh water and put them in the shade near pool area for our two kittens; now they don’t have to go in house for drink and love their time outside Great product then bring in,rinse out, and ready for next day or fold when dry and put away for next use!! Love them. [ I also float my gardenias in them for great fragrance around kitchen or outdoors around pool!!
