Rage, intelligence is much more fluid than being categorizeable species by species.
Intelligent organisms may adapt their cognition to associations they have never experienced before. Think of, for example, how an animal reacts to a window for the first time, hard transparent "air". This does not exist in nature, there "should" "logically" be no way for any organism to adapt to this. But they do, and quickly so.
So some cats can, some can not, look at human intelligence. We the range and variation is quite wide, even within a single neighborhood.
I guess I should narrow it down to intelligence that we can identify with then. That cat in the video is obviously having a realization that I thought only human babies and some chimpanzees were capable of.
I was wondering if this was more common than I thought.
hm, intelligence is incredibly difficult to understand because of several factors
1 thing is that everything we have, we inherited. so you shouldnt be surprised chimps got what we got, cus they got it first, then we inherited it. Even spiritualism which derives from creativity which derives from anticipation - is an intelligence trait common in actively hunting animals - anticipate what turn a prey will take: it imagines what hasn't happened yet, it guesses, it visualizes what is not yet true - what does not actually exist at the present moment.
2 you can and cannot precisely "imagine" how a cat thinks. The brain, thus perception of reality, will inevitably differ. Yet it will probably be similar, light, sound, thought-process, visualization, ideas and concepts, these basics go far back, deep into the roots of animal evolution.
3 intelligence comes down to necesity, but also sexual selection and many other factors. Human intelligence, you could say, has spiralled/evolved out of hand, since what was useful at first, has turned into dangerous delusions in many cases - all thanks to intelligence developing.
As a general rule mammals and birds are all intelligent, compared to the rest of organisms on earth.
Among the most intelligent organisms on earth are typically
Omnivorous, oportunistic and social animals (apes, corvids)
or
Carnivorous, actively hunting, tactics using - social animals (cats, dogs, dolphins)
These are often fewer in ratio than herbivorous animals, or insect or seed-feeding animals. Cows and horses are significantly less intelligent than most dogs or cats, but will still be einsteins compared to lizards. The span here is enormous, lizards are still highly cognitive and intelligent animals compared to for example invertebrates.
But even a spider will see you from a distance, recognize you as moving and large, thus scary, and flee, this seeing, registering, analyzing, understanding and reacting to something external.
