Keep your pet's water cool for hours at a time with this specially-designed water bowl. The inner bowl can be placed in your freezer to chill – fill it with water and it will stay cold for up to 8 hours. Holds 16 oz. Plastic and gel. 9 1/2"Dia. x 2 1/2"H.
Not worth the money
The bowl doesn't stay cool for as long as the item description states. You might get 3 hours out of it. Of course, it all depends on the ambient temperature. I returned mine. -
