welcome to Pettalk !!!!
I know the subject is serious , but I hope you do not mind I had a good laugh reading your story ... Isn't very nice , I know , but just imagine your story as a movie .......... !
Sorry if I cannot help you out ! Maybe you'd better get some advise at a rescue-shelter ? I am afraid there is not much you can do .. those kitties are all trying to tell the others : this is my spot , get away from here !!!
Lots of success anyhow !!
