If I e-mail a breeder and they do not respond within a few days, I just e-mail another breeder. If they do not have enough time for my inquiries, then they do not deserve my money either. I have had breeders e-mail me back weeks later. If they are going to e-mail this late, they should not bother at all. There are tons of breeders out there who have good customer service. I do not see any reason to deal with ones that don’t.
