The birds are entirely safe outdoors, and the outdoor feeding spot provides them with the 3 essential elements needed for survival, which are good, water and cover. The idea is definitely a win-win situation for both species. It is very easy to pick an area that will be appropriate from where your cat can observe. If you can establish a successful habitat for the birds that contain the three essential elements, and then reduce that area to a few feet around a window, you have found the perfect spot from which your cat can observe. Keeping cats indoors prolongs the cat's health and gives them a longer life span.
Birds are also safer when cats are kept indoors.
But, indoor cats tend to get bored or lethargic. This idea is especially beneficial for those cats that are at home all day alone. Watching the birds stimulates the cat and adds a extra excitement to their daily routine. Each tape has two versions, one with narration, and one with just the bird pictures and natural sounds. We find that our cat has a strong interest in the video with the background sound, and see the difference when the background bird sounds are played.
