Carnivore or herbivore? Which animal make better pets?

Dogs had always been man's partner when hunting. Being descendants of wolves, they were naturally carnivore. Smaller cats as descendants of the wild cats are also carnivorous by nature. They are both largely preferred by households because they are simply more beneficial to us. Dogs guard the home from strangers and cats chase away pests. If they still prefer eating meat all the time, I doubt that many households would keep them because that would be an inconvenience to us. Fortunately for us, domesticated animals have learned to adjust to the diet man can afford to give them.
