It all depends on the person. Some people could never love an animal as much as they could love a human. Some value animals a whole lot more than they value humans. Some see them equally. Everyone’s different. There is no right or wrong answer.
And despite what people may say (because I know that some will say it), no matter which of these describes you, it does not make you a bad person. It’s all about preference, and preference does not affect your character one bit. :)
