R and I took our dinner out to the lanai to eat where it was very peaceful and serene.We had seen one or two feral cats so knew that they were there. R said we must never feed these cats or we would never get rid of them. So there we were innocently sitting there eating our pizza when R looks to the left and sees a startling and unsettling scene. Staring at us in a stalking stance was a herd of approximately 25 to 50 cats. Actually, the ones we did see were just the scouts but we could feel the eyes of the entire herd upon us. R said, "OMG, look Sue!" Flashback of Alfred Hitchcock's, "The Birds!" Only with cats. Bravely, we had to pass through the herd to get back inside. I am thankful to report neither of us sustained any life threatening injuries in our retreat.
