Are there any uses of animal imagery in John Steinbeck's 'Of Mice and Men'?

Most often applied to Lennie, imagery is particularly apparent in his physical description. His hands are called "paws" and indicate trouble when he uses them. He lumbers along like a bear in Steinbeck's earliest descriptions of him. Lennie is also associated with rabbits, which are part of his dream (he will get to tend them on the farm) and because they are soft things he likes to pet. Rabbits also symbolise his realisation that he is in trouble; if Lennie does "a bad thing," George will not let him tend the rabbits. In the last scene, when Lennie is at the pool, waiting for George, a rabbit appears to him, berating him and telling him that George will not let him care for the rabbits. In addition, Lennie's loyalty to George is frequently described like that of a dog, especially a terrier. Steinbeck chose these images because they connote particular traits: unleashed power, conscience, and loyalty. In this way, it helps the reader understand Lennie and why he often acts instinctively.
