AUTOMATIC FOOD FEEDER - Designed using the principle of pressure difference, this feeder continuously provides food or water for your birds, helping ensure they stay fed even when you're away. DURABLE & SAFE - Made from high-quality plastic, the waterer and feeder are durable, resistant to cracking, and easy to clean. The transparent bottle allows you to monitor food or water levels and refill as needed. IMPORTANT NOTE - The feeder becomes heavier when filled with food or water, which may affect stability. Please verify that your cage bar spacing is compatible with the feeder's mounting frame before purchase. To ensure a secure fit and prevent leaks, the bottle mouth is slightly larger than the lid. Press the bottle mouth gently during assembly for proper installation. EASY TO USE - This parakeet water dispenser includes a fixed shelf that attaches securely to the cage, helping prevent birds from knocking over the container. The small outlet helps minimize spills and keeps food and water clean.
