During construction this past spring/summer, Sammy became an outdoor kitty. He's always, before this time, been content to be indoors. Now he's hunting birds in my backyard bird sanctuary. He's killed 2 birds now....yesterday it was a yellow rumped warbler. One of the prettiest birds, in my humble opinion http://www.pinebrookwetlands.com/photos/birds/Yellow-rumped Warbler.jpg Sammy tried to bring it in the house; in the meantime I'm between livid & in tears. How do I get Samson back into the house & content again?
