Hi there. We have lots of area bunnies but two outdoor cats just moved into the neighborhood. These neighbors don't take care of their dogs (fenced) so I know they won't keep the cats in. Fall and winter the cats tried to get adult rabbits, but now babies are available and easy prey. I can't blame the cats, they are cats, but I want to help the bunnies. What can I do in my yard to encourage and protect them? What shrubs do you recommend - placement?
