The simplest answer is to leave your pets inside. This is especially helpful during nesting season when baby birds are falling out of nests and learning to fly. While this may seem cruel to your pet, the reality is that it’s actually healthier for them as well. Most cats are expert climber, and they can climb up to bird nests to remove baby birds from nests. Another alternative is to equip your feline with a bird-proof collar. For more information about bird-proof collar, click here.
