Hi,
First, just wanted to send my sympathies. That is a really though situation and I'm not sure what I would do if it were me. I'm not sure I could ever pick one over the other.
I know a lot of suggestions have been given, but I wanted to encourage you to look into the Thundershirts. I am actually going to get one for my dog who goes beserk in the car; and a few of our clients have purchased them (for their dogs) and RAVED about the effectiveness. I browsed their website briefly and they seemed to be very present to answer posts/questions etc. I did see one poster ask about sizing for cats. Also, they have a 45 day money back guarantee, which they do seem to stand by. They are a bit pricey ($45 at our store), but if it works it would be a simple and drug free solution that should get fast results. Although Im not sure if it would mean that your cat would need to wear it at all times? Maybe at night if you crated the dog or the cat, then the cat could take the shirt off?
I was wondering, did the soft paws on your cats claws fall off? Or not work? Or was she able to do a lot of damage with her teeth? It seems like that would have been such a good precaution (protection) and maybe you could utilize them while trying out new things whether it is meds, the shirt or citronella collar etc
I second the person who encouraged research into cat rescues. I know many would not accept such an aggressive cat, but I do feel like they might work with you to help you find a home, they would have a lot more resources than you alone. Especially if you are willing to keep her during the search, or take her back if things did not work out.
They most likely have fosters who are cat savvy and may be willing to trial her in their homes. Also, they would be able to start fresh with her, not bringing in tense/fearful/negative attitudes towards her. Not sure if that makes sense? But they wouldn't have a history with her (besides what you tell them) and so she wouldn't be feeling the tension and anxiety that your family feels towards her since they are so afraid of her.
(EG, I know that when I am trying to manage a play group of dogs, if I am feeling jumpy and tense, the dogs feel that and are more on edge, high strung and the energy level and angst makes them prone to get into quarrels easier than if the humans were calm and relaxed)
Also, a slight side note, but about the shock collars, you are able to get some that have a VERY low shock level. I'm not sure if they make them specifically for cats (sorry I have a lot more experience with dogs) but we had a dog at work using one and my boss let each of us try getting shocked. Honestly I couldn't feel a thing when he "shocked me" even when he turned the rating up a level I still did not feel a thing. He told me that when the dog was shocked he could feel it, he acted alert, like if you had called to get his attention, but did not whimper, cry in pain or even act afraid of the collar. So anyways, not saying this would be a good alternative for your cat, but just wanted to give some info, because I was VERY against shock collars, but having tried one out, I am more open to using it in appropriate situations.
Also, not sure if you might want to try sectioning off your apartment? I have a studio myself, and when my dog comes to visit, my cat is relegated to my bathroom, and as it is only a day or 2 that is fine, but maybe you could effectively half your big room? with the cat having half and the dog having the other half? It is a small space but I assume you take the dog out for walks, and maybe you could crate the dog for few hours and play with the cat? There are quite a few products designed to keep cats out of an area, air blowers, citronella sprays, and I even saw "scatmats" which are electric mats, however reading the reviews made it does seem like the level of shock is decently high, as some of the reviews stated that if you accidentally step on it, that it is more than annoying.
Wow. Sorry that ended up so long. I hope that you are able to find a solution that you can feel comfortable with, whatever that solution may be. Even though we all have our opinions on what is right and what you should do, effectively it is your cat, and your life, and you are the one who will have to live with whatever you decide.
