That poor baby has been through a lot in the last few weeks. I would probably be hissing too!!
Thank you for helping her. That's wonderful.
Thank your brother too for fostering her.
Now...... she has been moved to three different homes in probably as many weeks, no? Who knows what happened to her before you found her. :sad: So the new owners should expect some resistance. She is feeling unsure, doesn't know if she is going to be able to stay at this house or if she is going to be moved again, is maybe afraid to get comfortable in case she does get moved........ get the drift? It is going to take her some time and a little extra loving from her new family. Extra loving does not always mean hugs and kisses. It could mean good food, fun new toys, someone to play with her interactively; like dragging a string behind them for her to "catch" or a laser light or something like that, catnip, etc........
Other questions..... Are there other pets? Are there children where there wasn't any before or visa versa? Has there recently been an animal in the house that she may still sense? Has she got her litter box in a place where she has complete privacy? Questions go on........
