I feel bad I never got any other pictures of the little torti - but guess what? She all of a sudden had no problem with petting, being picked up, she was playing and just doing great overall. A great family (so I'm told) decided that they wanted her. I heard she's doing great and that the family all loves her. She was such a cutie. I'm very happy that she was able to go to a good home. = )
The other two in this picture are doing not well at all. The little grey one has been nicknamed "Cujo." He is not socialized whatsoever and may not ever be. The LV's daughter will take him to her house when it is warm again and keep him as an outdoor cat. For now, he will stay with the LV's. The other little calico tolerates petting and will eat from your hand/fingers, but she hides all the time - and with Cujo, so I don't think they're sending the right messages to each other.
Personally, I think that if they're not good candidates for adoption, they should be sterilized and returned. They've already been in a home for a month - will that affect them negatively when/if they are returned? And it's not as if it will happen any time soon, so they will probably have been in a home for a good six months when/if they are returned. But the LV's want to give them time, and that's certainly their decision as it's their time and money.
