The Lucky Black C.A.T.

"There's no time for all this," said the cat. He cleared his throat dramatically. "I come from the Lost Land. No, don't interrupt yet, I'll explain. It's a place where everything lost from this world goes. Unicorns, dragons, spare change, socks ... You know how you always lose one in the washing machine? It goes to the Lost Land."A perfectly ordinary summer turns into a wild adventure, when Duncan and Emma meet a talking cat who takes them to a magical other world, under attack by werewolves, and they find out that they might be the only ones with the power to save it.
