Add food cups to your Wingdow® Lite if you want to give your little bird a treat while he/she is perched on Wingdow® Lite. The cups that fit Wingdow® Lite are made of durable, bird-safe, and dishwasher-safe clear plastic and hold 2.5 ounces of food or water. The transparent design allows you to view food/water levels and replenish as necessary. Each cup fits inside a stainless steel ring that attaches to the back of your Wingdow® Lite. There’s room on the back of Wingdow® Lite for attaching two cups. Cups slide out of the ring for easy cleaning. Can be used in your bird’s cage, as well as on Wingdow® Lite.
