Look at this web site and do some research on how big cats see in the dark.
Once you have looked at these websites I want you to do this craft, when you're done show Mom.
Get two sheets of black construction paper and one sheet of yellow. Then cut out three pairs of cat eye shapes from the yellow paper and paste them onto one of the black. With the remaining black paper, cut out shapes of a cat's eyes slitted, medium dilated, and fully dilated. see the first web link above for examples.
