What figurative language does this poem use and where?

The fog comes in

on little cat feet

It sits looking

over harbor and city

on silent haunches

and then moves on

Animalification is the figurative language. It is used when saying how the fog comes in on little cat feet. Then it goes on by saying it is sitting down and looking over something. If animalification is not an option then it is personification, as animalification is a more narrowed down term of the aforementioned used to describe the actions of an animal as applied to the inanimate object.
