Ultimate proof that cats are smart !!! more smart cats«
Cat intelligence is actually a pretty interesting topic in that the majority of studies on the subject basically have to end in the conclusion "we just don’t know" because cats are among the most uncooperative research subjects of all time. We know a great deal of cat sight, having used cats as the archetype for a vision-focused vertebrate/mammal, but we still know very little about what really goes on inside the cat mind.
