While it may be tempting to raid your pantry and use leftover food like old bread, nuts and snack food to feed wildlife, it's actually doing more damage than good. According to the Humane Society of the United States, "people food" can be unhealthy for wildlife and hurt their digestive tract when they eat it. Plus, feeding wild animals close to your home lessens their fear of humans, turning them into wild panhandlers. But you may also be inadvertently feeding wildlife without realizing it by feeding your pets outdoors. If the family dog doesn't finish his food, it becomes a tempting food source for wildlife. They'll eat it and keep returning to get more. So feed your dog indoors to prevent that from happening.
