AUTOMATIC FOOD FEEDER - The feeder, designed according to the principle of pressure difference, can continuously provide food or water for your birds, ensuring they always have access to nourishment even when you're away. DURABLE & SAFE - The bird waterer and feeder are made of high-quality plastic, suitable for making food or water containers. It has a certain degree of flexibility and is not easy to crack, making it durable and easy to clean. The bottle is transparent, allowing you to monitor the food or water level and refill as needed. IMPORTANT NOTE - Since the feeder becomes heavier after being filled with food or water, it may not be securely fixed in the desired position. Please confirm whether your cage gap matches the size of the fixing frame before purchasing. To better fit the bottle body and lid and prevent leakage, the size of the bottle mouth will be slightly larger than the lid. When installing, please slightly press the bottle mouth to assemble. EASY TO USE - This parakeet water dispenser comes with a fixed shelf, which can be attached to the cage to prevent your bird from knocking over the food bowl or water basin. The small outlet helps prevent food or water from overflowing, keeping everything clean.
