Like Cats & Dogs

A Hallmark Channel original movie. A reservation mix-up forces two young vacationers and their beloved pets to share the lakeside house they had each rented privately; between his finicky feline, her calamitous canine, and two pet owners who seem to have nothing in common, it is a recipe for disaster. But, just as the four-legged occupants soon learn, friendship – and perhaps more – can be found under the most unlikely of circumstances.
