When Pi's father teaches him a lesson about tigers, The goat is tied to the outside of Richard Parker's cage. In the following scene, Richard Parker is dragging "his prey", apparently having pulled the entire goat through the cage's bars. The goat was far too large to be pulled through the bars.
Early in the movie, Pi says that Hinduism has 33 million Gods and Goddesses. In Indian English, the word 'crore', which means 10 million, is used rather than million. A fundamental belief in Hinduism is that there are 33 crore Gods and Goddesses. This converts to 330 million, not 33 million. (The use of million rather than crore may be a translation for the benefit of the audience, rather than a goof.)
