Well, sort of. Dogs and cats are both mammals of the Order Carnivora, which means they eat meat and will hunt to get it . In the wild, sometimes that means canines eat felids and vice versa - lions tango with African painted dogs, wolves munch on wildcats, tigers pick off neighborhood strays, coyotes abduct alley cats, and on and on. But out there, cats and dogs don't "hate" or "love" each other more or less than any other species. In fact, both would probably rather avoid the other and pick on easier prey.
However, cats and dogs are forced to interact when we bring them home and plop them into our living rooms. And that's where the miscommunication begins.
Dogs and cats approach the world in very different ways, says Pam Johnson-Bennett, best-selling author of cat behavior guides and host of Animal Planet's "Psycho Kitty." "There's a reason there are no cat parks in the world," she points out. Cats like to hang back and assess the situation. She says it's not that cats are antisocial or mean, just that they take a lot longer to warm up.
On the other hand, dogs will typically charge right up to a new person or animal to investigate. Johnson-Bennett says the cat interprets this behavior as a possible threat and instinctively tries to climb or run away. Unfortunately for the cat, running triggers a chase response from the dog, and the whole situation rapidly deteriorates into a cartoon scuffle cloud.
