I was just watching Tomnus jump from the floor to the counter and land, I'm assuming, right where he wanted to go and it dawned on me. They do what we have to work out(trajectory and such) in there heads. That proves to me that they have increasable intelligence. If you doubt that come over to my house and watch Tom try to get into the box of teats that I have on my filing cabinet. He will try for hours to get that thing open and you can just tell he is deep in thought.
