Many neighborhoods have hawks who linger about the area. While they mostly prey on small rats, squirrels, and other birds, they will make a meal out of stray animals. If you have a pet, keep them inside or on a leash, secure all holes in your backyard to limit the exposure range, and for extra security, you can get a raptor-proof vest for when you walk your small dog. Making small changes in human behavior helps us coexist with our native critters. It also helps keep them on a diet that may just get rid of the invasive rat species.
