Hi Jenn, I've been reading all of the posts in this thread and though I am not able to take in another cat at this time, I'm hoping an idea I have might help. I'm wondering if you think some Clomicalm might help Ally? I have two bottles of 5mg Clomicalm (60tabs) per bottle that were prescribed for my cat Paddy in mid October for aggression. Things have settled down here without needing the meds and I'm not sure if it's something I'll need to try with Paddy in the future but for now, the bottles are just sitting here gathering dust. One bottle has never been opened and the other is only missing one tablet. I know that it may not be ethical giving meds that were prescribed for one cat to another cat but in this case maybe it would be okay because Ally's options are so limited. I would be more than happy to mail them to you and who knows, maybe it will soften her personality enough to at least make her temporary situation with you more tolerable and her potential future living arrangements, wherever that may be, more comfortable for her. It sounds like she is dealing with issues that stem from once being feral and maybe she is angry for being 'abandoned' and this might not be an answer but it might take the edge off and make things easier.
Anyway, if you would like to give it a try, just let me know and I will send them in the mail tomorrow. I wish I could do more to help. Hope things get better for both you and Ally.
