"Cat" is a dog, a bloodhound and golden lab mix, living the good life on the rural south end of Whidbey Island in Puget Sound. "Dog" is a calico cat living under the same roof; she is aloof as cats are prone to be and a little on the wild side, keeping awful hours and dragging home her "trophies" from the ferry dock. Twelve-year-old Vicki Townsend loves both her pets dearly, but she shares a secret with "Dog" that "Cat" must never know. Never When a mountain lion terrorizes the island, preying primarily on the island's domestic pet population for breakfast, lunch and dinner, Vicki's worst nightmare comes true: "Dog" is forced to reveal Vicki's secret to "Cat," bursting "Cat's" idealistic bubble and proving that something indeed is rotten in the State of Washington. After such a devastating revelation, will "Cat" swallow his pride, put aside his hurt and help rescue "Dog" from the jowls of the vicious cougar? Only time and "Cat's" keen sense of smell will tell.
