Read the following passage What does the fox symbolize in Ted Hughes poem The Thought Fox?

Read the following passage carefully and answer the question based on the passage : 
The Thought Fox is One of the early and most favourite poems of Ted Hughes (published in 1957). This Poem is symbolic of the process of poetic inspiration. The symbolism of poetic inspiration is concealed behind the animal imagery. The fox in this poem represents the poet’s imaginative powers. The poet goes through a special kind of loneliness; this loneliness is not the absence of people around him, but the absence of Creative powers. His fingers move , but the pages remain blank. The poetic inspiration in the poem, which is represented by fox, appears in the poem part by part. It does not appear in full. sometimes it’s nose images, Eyes, it’s prints, or the Shadows. This is a perfect illustration of how our poetic inspiration comes, i,e., any literary composition is produced in parts; it is seldom written in one sitting or in one go.
