The poem is about a dance between lovers - the cat here represents Yeats, the author, whilst the moon would be Maud Gonne, his supposed muse and love of him -, and may also hint at the Romantic concept of mutability.
“Stared at the Moon” / “For wander and wail” – These phrases show that Yeats’ love for Gonne controls him. He is always looking out for her, even though the physical distance between them will always be too far.
“Animal blood” – Yeats bestialises himself as Minnalousche (thought to be the name of the cat Yeats based The Cat and the Moon on), perhaps to suggest that he is not in control of himself when it comes to Gonne – he is driven by his more primal instincts.
remote means having very little connection with or relationship to. so the thing is remote meaning its never had any actual connection to anything making it fearful.
