I loved it. He uses animals for symbolizing human nature & also nature of world. In his poems we can find the reality check about this worldly life. Pike is the very first poem I have read. He was interested in primitive themes : nature, war, sex, death. It's not true he is an animal poet or nature poet though we got so many senses of these things. Above all I can say that he is one of the best poet I have ever read in English poetry.
