Do you have any idea why they are picking on her only? I'm just curious to know. Is it just Noah getting more aggressive and the rest are just joining in or is it something specific about her?

Since you are already using feliway and more I really have no suggestions except to separate her within the house but that's not much of a life for her either.

I really hope you can get this worked out and I hope someone has some wonderful wisdom to share with you, unfortunately I don't.

Poor little Olivia. That picture of her looks so much like Jazz when she's on her bed.
