Drinkwell Hy-Drate. Pets need clear, clean drinking water in order to stay healthy and hydrated. The Drinkwell filters are designed to move and filter water so that cats are encouraged to drink more of it. The system fits in most pet bowls, and it circulates water quietly so that it simulates the sounds of water in nature. This tempts cats to drink more water so that they are less likely to get dehydrated and suffer from urinary tract infections. It is dishwasher safe, and it has an adjustable flow control so that you can set it to match your pet’s needs. $22. BUY. via MyCatGoma.com.
