On the journey to America though Fieval loses his parents and arrives in the New World all alone. To add further misery in Fieval America is not all what it is cracked up to be...there are cats there to! Fieval never gives up hope though, and with his new found friends he begins a search for his parents, all the time dodging the cats he thought he'd be long rid of.
