When you're small in the city, people don't see you, and loud sounds can scare you, and knowing what to do is sometimes hard. But this little kid knows what it's like, and knows the neighborhood. That makes for some pretty good advice for a small feline friend.
Like, alleys can be good shortcuts, but some are too dark.
Or, there are lots of good hiding places in the city, like under a mulberry bush or up a walnut tree.
And, if the city is too loud and scary, a small cat can always just go back home, where it's safe and quiet.
