ICE COLD WATER FOR YOUR PETS - Double-walled stainless steel freezer bowl is perfect for keeping your pet cool on hot summer days. Simply put the Polar Bowl in the freezer the night before and then the next day fill it with water. The Polar Bowl keeps your pet’s water cold for hours. DOUBLE-WALLED STAINLESS STEEL WITH GEL CORE - The secret to keeping your pet’s water so cold is the double-wall construction with a gel core in between layers that freezes just like an ice pack. The double-wall construction ensures that the gel doesn’t seep out, but to give you peace of mind, the gel is non-toxic. COLD WATER ENCOURAGES DRINKING - Colder water is actually healthier for your pets because it encourages proper hydration. USE INSIDE OR OUTSIDE - Quit putting ice cubes in your pet’s bowl that just melt away in minutes. With the Polar Bowl, you can keep your pet’s water cool even outside. The Polar Bowl is not just for outside, though. Pet’s love cold water year-round, so use it inside, too, in the cooler months to encourage your pet to stay hydrated. COMPATIBLE WITH MEDIUM-SIZED NEATER FEEDER DELUXE - The Polar Bowl will fit inside of the Neater Feeder Deluxe for Medium Dogs. It does NOT fit inside of any Express model or any other size of the Deluxe. Don’t have a Neater Feeder? Not a problem. The Polar Bowl can also be used on its own as a standalone bowl. Polar Bowls hold up to 3.5 Cups (28 Ounces) of water. Polar Bowl by Neater Pet Brands
