A cat water fountain encourages cats to drink more water, which helps with their overall health. I’ve noticed an increase in my cats’ water consumption since switching to a fountain. Fear not WIRED-heads, these aren't pet water bowls of yesteryear—these techy fountains I tested are often connected to an app, which reminds you when to clean, replace the filter, and refill water.

Updated May 2025: We've added the Petlibro Stainless Steel Fountain, Brook Glass Pet Fountain, and Homerunpet Wireless Pet Fountain, removed the Petlibro Glacier Ultrafiltration Fountain which seems to be discontinued, and updated links and prices throughout.
