We kept Perdita because we love her dam, and her full sister is also really nice!  Perdita is longer in body than either her dam or her full sister.  She is very sweet and genlte in personality.  Her FF udder is very nice and about the only thing that I would change on it is her teat placement.  Height, shape, texture, and attachments are all there.  And I am pleased with her production as well, giving me 2.9 lbs on her first 12 hr fill.
