assessment of intelligence is often based on comparing animal intelligence to human intelligence. Dogs are adept at communicating in ways that humans understand. Cats, on the other hand, have an unhuman mind, and don't seek empathy the way dogs do. They do it in a cat way. To understand the intelligence of animals, truly, we should let go of our notions of human intelligence, and seek to enter animal perception as it is; not to correlate our perceptions with theirs, which would limit our understanding.
