They're relatively smart in that they can quite intelligently navigate their environment to best get at prey that might otherwise kill them.

Really, all animals are relatively smart (ignoring individual differences in a species), in that they have specific skills and abilities that allow them to be most effective for their biological makeup, and purpose in their respective ecosystems.

We humans are no different in that regard ~ we are relatively smart, in that our biological makeups grant us leanings towards skills and abilities that other animals don't have.
