Not to put a dampner on things but certainly Nina, my Siberian, came to me because the man who had her had got her with the belief she was hypoallergenic - she wasn't.
I am also, judging by my cream bedroom carpet, not quite believeing that they are meant to shed less! Nina sheds less than Edgar - but then I think every cat sheds less than Edgar!
Hope the little lady gets something soon - Siberians are just gorgeous!
