Not sure what to do really. She just doesnt seem to be fitting in very well with others. She keeps attacking them and me. Just picked her up now and she has sank her teeth into me again and she is nasty with it. My old cat has stopped coming in all together as she is attacking her fur all stood on end and really hissing at her as she is getting older she is getting worse not better thought it might calm down but its not. I know the kids will be upset but im worried she might turn on them and make a mess of them. They will be upset for a while but at least we will still have others really worried that they will disapear if it carries on.I have bought a feliway plug in and that has done nothing other in regards to her attacking but has stopped roony weeing in house so at least its had it benefits . With not knowing her background its hard to say why she could be doing this . Need advice please
