Brain size

Within the encephalization quotient proposed by Jerison in 1973, values above one are classified big-brained, while values lower than one are small-brained. The domestic cat is attributed a value of between 1–1.71; relative to human value, that is 7.44–7.8.

The human brain is about three times as big as the brain of our closest living relative, the chimpanzee. Moreover, a part of the brain called the cerebral cortex – which plays a key role in memory, attention, awareness and thought – contains twice as many cells in humans as the same region in chimpanzees.

What is the smartest animal in the ocean?

It's estimated that dolphins have an IQ of around 45, this makes them one of the smartest animals in the world, and probably the smartest animal in the ocean. It's estimated that the dolphin's brain size is almost five times bigger than is usual for a creature of their size.

This makes it obvious to see why we never managed to domesticate them. There were several attempts, however, but they all failed. Many attempts ended up with humans being killed by hippos.
