You can get just a year for killing an animal, and killing animals is LEGAL in many situations without a consequence. You can also get life in prison for killing a person, and life in prison for medicinal marijuana. There are people who continue to do horrible things to animals, and get away with it. So yes, animal cruelty laws do need to be stricter. Humans are not in any way less or more important than animals. We feel pain, just like they do. Today in the US, every law is either unnecessary, too harsh, or too lax.
