noon
Have you ever looked at your cat 's eyes ? How well she sees in places that seem dark to us ! In what way are her eyes different from ours ? At noon , the black spot in a cat 's eye is only a narrow slit , but as the light grows less bright , the pupil of the eye grows rounder and larger . In this way her eyes gather in more and more light as darkness comes on , so that at twilight she can easily find her way . When it is really dark , her sensitive whiskers help her to feel what she can not see . Pussy 's tail is part of her backbone or spine , which is made up as carefully and delicately as our spines are .
