I would like to add that I too would contribute towards either another reading or a vet visit or both. Having these things done wouldn't do any harm and maybe, it might result in some kind of resolution which would be such a blessing. Perhaps having her examined from head to toe under some sedation would provide some information otherwise unknown.
My husband and I are moving soon and we are hoping to find another home with acreage. Part of me wonders if I couldn't somehow make a space for her, with her own little outbuilding with heat and a large enclosed run where she wouldn't have to deal with other cats. My other cats have a super big outdoor run right now (70 feet by 20 feet) and they seem to really like it. But making her travel again might set her back even further and who knows what my husband would think about this idea! I don't think he'd be keen on it but I might be able to talk him into it. But if there is even a possibility that I could do it, it wouldn't be for months because we're listing our place this Friday. It would also depend on if we found another place that has acreage or not.
And of course, it may not be something that Jenn feels is right for Ally. It just breaks my heart thinking of this poor soul, feeling so angry/upset and not being able to find a way to be any different.
Jenn, does Ally come at you (in attack mode) when you just walk in the room sometimes or is it usually related to when you are about to touch her or move her? Does eye contact set her off? I'm just trying to get a better idea of how she is.
Anyway, in the meantime, I hope the Clomicalm will make a dent and get her to the next point whatever that might be. My thoughts are with you Jenn.
