There's something unusual about the kitten Memo finds in his yard.
Memo lives in a small cottage with his grandmother. But his grandma can't see very well anymore, and she falls asleep all the time. Memo starts to feel a bit lonely...until the night he discovers a stray kitten. The boy and cat become fast friends. But as the cat grows and grows (and grows), Memo realizes that this kitten may not be a cat at all. And it most definitely doesn't belong in a cottage! Memo needs to make a plan so that his friend can get home safely. What will become of his big, furry friend?
