I also agree with what you said regarding the influence a male figure, wether a father or somebody non related, has on young boys. I think that the environment in which kids grow up in and the actions of those who they look up shape their perception of a real mean. Have you ever noticed how much of an impact athletes have on how boys carry themselves? If Stephen Curry demonstrates that he can overcome adversity, then boys are encouraged to do the same as their role model. If Kobe Bryant cries while talking about his career, then boys hope and strive to have as much passion as he does for basketball.
As for the animals, I used to have a hamster named Gus Gus! I don't know if you have ever seen Enchanted, but even in a non cartoon Disney
