"Ngo said her rescue has become so busy that it’s had to stop accepting owner-surrendered bunnies. Right now, she said, Hoppy Hearts is only taking in rabbits that have been abandoned outside."

That seems to be a mis-allocation of resources. It is a lot more work to capture an abandoned bunny, and what do they think happens to their refused bunnies? Best-case scenario is for the owner to arrange with a friend to abandon the bunny at the friend's place, and the friend immediately phones in the existence of an abandoned bunny.
