Excellent, my cats love this.
I've had this now for a good few years, at least 3 I think. My cats love it, it's lasted really well, it's outside all year round, I clean it regularly as it gets algae growing on the inside and gets full of leaves etc but they love splashing around in it and drinking from it. The little floaty things are long gone, my Mainecoon used to fish them out and hide them. Would absolutely recommend this product. Will probably buy another one with my next order ready for the summer.
