I think with only having 2 the cat wont be scared off. I think the cat attack might have been more of a play time for the cat. If I wouldn't have seen all the feathers on the ground I wouldn't had known anything happened. I dont think the cat meant to do harm or I'm sure she would have been dead.Glad your girls are safe. This is the hardest time of year. The camera sounds like a good idea. Usually cats learn to stay clear of full-sized chickens. We have a few that roam the area & I've seen them watch from a fence about 100' away. They have never come any closer and certainly never ventured into our yard.
