There are deleted scenes
1) An extended scene where the birdwatcher brings Sassy to his house, he tells his deer neighbor who hangs around his yard that "they have a guest."
2) After finally returning to civilization, before they get to the train tracks, the three are walking down an alley and Chance is complaining about being too hungry, Shadow agrees with him and suggests sending Sassy into a dumpster to look for food. Surprisingly instead of refusing to do so, Sassy agrees and says something about a "cat gourmet." The next scene shows a dumpster with cans being thrown out, we hear Sassy going "empty, empty, empty." The three do not find any food. The gang now reaches the train tracks.
