These cups are made here in the United States by a small company that has been in business since 1974 producing this line of feed and water containers for caged animals and poultry. They have a Unique shift locking design that keeps more active pets from knocking them off the wire. Containers are both boil & freeze resistant for strength and sanitation. They are a thicker, more flexible plastic, and consequently are not prone to freeze and bust like all of the imported water cups that I have purchased from Randall Burkey, Belle Farms, Cutlers, Jeffers, etc. in the past. (For ice removal & to prevent breaking, it is best to fill only 1/3 to 1/2 full in the winter.). Returned items are subject to a 20% restocking fee.
