Bests & Worsts Reviews from Amazon

We used the fountain about a week and I noticed my cat was acting weird- lethargic and vomiting. I recently changed his food so thought it was that and changed it back. I cleaned his fountain and noticed little black specs which is said is normal, so cleaned it just in case. This time I cleaned it and there are little bugs crawling all over the filter. So disgusting and I bet it’s what’s making my cat sick. So disappointed because he loved drinking from it at first.
