I'm lucky I guess, the Potty Area (back yard) here (via Doggy Door) has a very heavy canopy overhead. Just impossible for a predator to "swoop" in and have a line of exit. Besides Sneakers and Becca being larger Yorkies, the Hawk they killed had to "navigate" the foliage as it approached, and that's probably what alerted Becca to grab it. She doesn't care much about Squirrels, but Birds are first on her list of territorial violators.
