I got mine from a then she changed to a UFo-tchi. How I got my furwatchi was being a tiny bit forgetful of the stats(but took very good care of her otherwise), fed her snacks, but didn't let her get overweight.
I HAVE a Furawatchi right now! Well, first try to get a boy Cho Himetchi then a girl. Take regular perfect care and there you are! That's how I did it. don't PM me saying it doesn't work, k? I jus' do what I can.
