Also, dogs are actually much more intellectually capable than cats, despite that cats have that look on their face like they know whats going on.
Just because a cat doesn't feel like doing a trick doesn't mean it's less intelligent than a dog. It's like someone coming up to me and saying hey you have a BFA degree? "Tell me everything you know now in order to get that and I will give you a cookie." And then I respond by ignoring them because I don't feel like answering the question. And then that person says, "WTF, answer my question or I'll take that degree away from you.
You know what never mind I'm just gonna classify you as less intelligent."
It's this type of thinking that has led to graduate degrees rewarding people who can wiggle through the system rather than on their intelligence and innovation and creativity.
FYI, I don't eat pork because I am against eating intelligent animals. A pig is much more intelligent than a dog...in fact they can play atari-like video games and a full grown pig has the intelligence of a 4-5 year old human.
