Multiplication Challenge

My husband offered me this brain teaser at lunch the other day. (I was successful on the second try! No hints! :o) I thought you might have fun trying it with your children. It will help them practice their understandings of multiplication. They can certainly use a calculator - we haven't taught them to multiply any more than single digits. Let me know what you come up with!

There are 7 girls on a bus.
Each girl has 7 backpacks.
There are 7 big cats in each backpack.
There are 7 little cats for every big cat.

How many legs are on the bus?
