Cage is signed by taking both open hands with fingers spread, and tapping the fingers against each other at right angles. The sign looks like you are making the intersecting bars of a cage with your fingers.
If you have a pet bird, you can teach your baby that the bird lives in the cage. You can also use the cage sign for a dog's crate.
If you are lucky enough to have a little bird or other small pets, you need to include the sign for cage in your baby sign language learning program.
