Cobectal Stainless Steel Cat Water Fountain 74oz/2.2L vs PetSafe Drinkwell Platinum Dog and Cat Water Fountain

The Cobectal stainless steel cat water fountain is built from durable 304 stainless, runs under 30dB, and pushes water through triple filtration that strips out impurities and odors. Its 2.2L capacity covers an adult cat's drinking needs for 5 to 7 days. Reviewers note it effectively prevents black chin and that the water level is easy to keep an eye on. A 2-year warranty comes with it. The pump's external foam filter needs cleaning often, and only the bowl and lid are dishwasher safe.

At 168 oz, the PetSafe Drinkwell Platinum Pet Fountain holds enough for several pets, and its automatic refill reservoir snaps onto the back to top the bowl up. Reviewers noted the adjustable free-falling water stream entices pets to drink more, and a built-in carbon filter keeps the water fresh. Most parts go on the dishwasher's top rack; the pump has to be hand washed. It needs to be plugged in, and that separate pump cleaning is an extra chore. Owners who want a reliable automatic fountain with good capacity and filtration are the fit.
