How do you get rid of the mama cat in animal crossing wild world

You've Wi-Fied with a friend recently, right? Get that firend to Wi-Fi with you again. He/she SHOULD have the baby cat in their town. Reunite the cats. One of you will get a prize. And the annoying cats will be gone.
P.S. You're lucky you got the mom. The baby kitten is SO annoying.
