It's important to remember that some animals may be obligate carnivores, meaning they *must* eat meat to survive. Others might be facultative carnivores, meaning they primarily eat meat, but might occasionally eat other things like plants or insects.
There are also many animals that are omnivores, meaning they eat both meat and plants.
