This feeder system has all the features necessary to feed your pet in a safe and sanitary manner. No need to worry about letting guests take care of your pet while you are out of town, with the removable dish you will be able to change the food and water without having to open the cage and allow contact with the pet or possibility for escape. This system is designed with extremely durable materials for large destructive birds (such as Macaws) and also works great for venomous or other potentially dangerous reptiles. The hood is clear so your pet does not feel confined while eating, yet the dish has a slight tint to conceal mess (color of dish may vary slightly from picture). External mounting also ensures birds or other animals do not waste in their food or water. This system is intended to have a separate feeder for each food an water application to prevent cross contamination, making it more sanitary than other feeding methods (each feeder sold separately). Can be mounted to any of our stainless steel wire or laminate panels (we cannot mount to acrylic) or can be retrofitted to many other cage systems. Order the cage from us, and we will fabricate the mounting holes for free (please make sure you let us know where you want it mounted). Each Friendly Feeder comes with one removable dish, extra dishes available to use while cleaning (dishwasher safe). Dish is approximately 5 1/4" x 5 1/4" x 2 1/2". Friendly Feeder Perch also sold separately for easy, comfortable access to feeder for birds. Mounts easily to wire sides with bolts and wing nuts.
