Designed to meet the needs of ducks and other waterfowl with longer bills, but also works great for chickens or pigeons. The built-in hooks allow for secure attachment in cages, preventing it from moving or tipping over during use. This not only minimizes spills but also ensures that the water remains clean and accessible at all times. Made of durable plastic and easy to clean, this cage cup can also be used for feed. Great for show season since its lightweight design makes it easy to transport and place in different locations. Holds 12 ounces.
