Unfortunately, no. Animals that are in the city must remain in the city, and will not come to live in your town. They have a house, too, and aren't about to complicate their lives by moving to your town.
However, some of the animals in the city may move into your town, but they will not disappear from the city. It just so happens that the list of characters that could move to your town also appear in the city.
The only time animals come into your house on Animal Crossing: City Folk is when it is a Flea Market day. Only one animal can come into your house at a time during the Flea Market.
you cant get them to come. the better your town is the more of them come. basicly they come on there own. from just a random guy who playes animal c.
Animal Crossing City Folk will never come out for the DS, DS lite, or DSi - it is strictly for the Wii console.
