I wouldn't call her heartless. At least she seems interested in learning about them now. I agree it's wrong to buy impulsively without learning about them first, but I think the true crime lies with the breeders and petshops who breed and sell irresponsibly.
Lots of people erroneously think if they go to a breeder, or petshop, everything is fine, and are suprised to find out the info they were given was wrong.
I'm going to presume that she meant well, since she seems keen to learn. Golfdiva, are you going to point her to this site? Hopefully she'll go to a rescue now, and learn the true joys of healthy bunnys!
