Although spring is typically seen as a time of rebirth and regeneration, the season also can bring doom for birds. Many of them become vulnerable to uncontrolled cats as they prance about a lawn or back yard looking for nesting materials or food.
Studies by ornithologists show that bird watchers would have millions of additional birds to enjoy if it were not for uncontrolled cats, a constant threat as long a birds remain in an area.
Studies indicate 40 million cats are permitted by their owners to roam freely, and another 28 million cats roam freely because they have no owners. Together, they annually reap widespread destruction on birds and mammals alike.
