We are animals

Scientifically it's been proved that rats laugh
Rats can sing songs (ultrasonic) 
Rats have complex thought like dolphin and humans
It's been proved that can be altruist with other members of their community 
And this is mostly because most research is made on rats. I can tell you I have two, they are amazing, but you see, many animals that "human" understimate are not so different. Same I can say about Kira and Totonika. Having my pro-animal moment. When I see my babies I see they have two eyes, and two ears, and a beating heart, and breathing lungs and a thinking brain, and dreams when they sleep, and somehow I am happy, not because I am a human but because we are animals.
