In my philosophy class, we are being taught that animals do not actually have any intellect and act only upon instinct.
I'm unsure of this right now, especially with all those stories and videos of animals transcending their so called limitations. Here is a video of a comedic interaction between two animals. There are a lot more interesting videos such as heroic pets and the like, but I think this would be more useful for cheering up :)
