Pregnancy Hormones

Second post today. I just had to talk about this though, so I'm sorry if it's short...
My parents and I were watching a movie called Rise of the Planet of the Apes. (Spoilers follow) At first, I really liked the movie. It was interesting. For a girl with Asperger's, it was relatively easy to follow. Especially since it had animals. (Not all Aspie's necessarily like animals, but I do.) Anyway, it centers around one ape/chimpanzee named Ceaser. He was basically family to a character played by James Franco, and referred to as his son. Now, some things happened that cause Ceaser to be placed in a "sanctuary" where he was treated horribly by Dodge, played by Tom Felton. At one point, Dodge sprayed Ceaser with a fire house. Poor Ceaser was in a soaking wet shirt his "father" gave him, in a soaking wet cage, with concrete as the floor. When he curled up on the floor, obviously looking depressed, I started to feel my eyes watering. Then when Ceaser found a rock in his cage, he used it to draw on the wall. He drew a window that was in his room and his home, with his "dad"... that's when I lost it. Started crying a lot. Bawling really. I had to leave the room. Then my mom had me go with her to her room to calm down. I was cuddling my puppy, Luna, and I was still crying. Cried for about 20 minutes after. Needless to say, I didn't see any more of that movie, nor do I plan to.
This is supposed to have been brought on by my pregnancy hormones. Which I can believe. But, I wonder if it had to deal with my Asperger's and love of animals. Like, I knew the movie was fake and that Ceaser was played by a human, but I couldn't help it. Especially knowing that people test on animals, who are probably treated like this. It's just not fair.
