Animals are just animals, the 'sweet and adorable' is parts of your brain selected by evolution to induce you to care for human babies being triggered by certain physical characteristics. If you use your whole brain you can direct this response rather than letting an evolutionary subroutine direct you.
You can never realize your true potential at a human being until you stop allowing instinctive impulses free reign to direct your actions. Your instincts are like an animal which you must train and condition for useful work rather than allow to run wild and get you into difficulties. I'm not talking about repression, you shouldn't just repress instincts but direct them to channels which promote harmony with other instincts, your environment and situation. The refusal to see ourselves as impelled mainly by instinct and to do something about it is at the root of many if not most of our personal problems from obesity and financial mismanagement to failed relationships.
A good part of the problem is our culture is stuck on the Romantic ideal of instinct and emotion being the path to satisfaction. It's an idea so ubiquitous, so incessantly broadcast at us in all media it can be hard to imagine there is any other possible way to live. It is promoted by commercial and political power because impulsive people are easier to manipulate into decisions which serve those powers interests.
