Carnivore or herbivore? Which animal make better pets?

Being on the top of the food chain, most humans seem to respect other predators or at least like them better. On Animal Planet channel, every time there was a chase going on between a predator and a prey, my mom used to swear the voice in the background was always on the side of the predator.

Most people also believe dogs and cats make the best pets. I guess they would vote for predators. I have the plan to get a cat myself, just because they are cute and can be playful, not because what they eat.
