Mia still hasn't got over her cat's death - she had Tibby for as long as she can remember and can't ever imagine having another pet.

But one day, just before Christmas, she finds out that her friend's cat has had kittens. Over the holidays she goes round to play with them. Mia's parents think she has coped with Tibby's loss, and surprise her by saying she can have the last kitten, Whiskers.

Mia's not sure she's ready yet - although she loves Whiskers, she feels guilty about Tibby. Can Mia bring herself to keep the new kitten?
