Sorry for being off the topic here. I guess that I was tired when I posted this.
I haven't had that situation as of yet. I've been offered other animals and I turned that down because I don't think that my cat will be able to get along with them at this point. I have thought about it and realized that if I were to do this that, I would have to break the other one in gradually. because the older one will have herself in a scary transition.
Hopefully this helps you. Your older cat is going through a transition now that she has to co-exist with two other cats. Her environment was changed on her, not by her choice. Animals are extremely territorial. Before she was the only one getting all the attention. Now having to share the attention and her territory is scarying her. That's why I think that you see the behavior change in her.
As humans, we have control when we have to go through transition. It will usually take anywhere from two weeks to a month that we get ourselves though it in a healthy matter.
As cats and dogs, animals don't have this control. So they could be going through transition for months getting themselves used to co-existing with other the animal. My suggestion is to just be consistent and a leader when they need you to be. Love all of them. Pay attention to all three of them. Give each of them there space, even from each other. Until they are ready to co-exist together. You could award them for all the positive things that you catch them doing for each other. Even if it short lived. That could strengthen this for them.
When they see that you are there for them, that enables them to work through this transition, I think. I believe that cats need this assistance. In the end, it will workout. Susan
