Also there are some people who prefer to bred on alts OR in the case of the special babies that were limited to one per avatar I know I and others would give our breeding cats to alts until each got one as a small workaround to the one per avatar. I would personally NOT want people to know who those alts are as they are private and used for other business and personal things but now either I get to NEVER sell cats from those lines (which I already have done) or hey there is Sanura's alt *shrugs*
Edited to make this clearer. I have bred on an alt a few times, KittyCatS is now showing that avatars name which before now has always been kept quietly hidden behind the scenes because the cats went back to me and showed me as owner. Now it is quiet obvious that I bred the parents I own the babies so that second avatar who so called "bred" that kitten who I now own as well, is me. Honestly had I known this would have came out I would have NEVER used alts to bred as I do NOT want people to know who they are for my own personal reasons and it is no ones business.
