They will figure this out. I have the same thing from time to time. I make sure that when I do have the opportunity to have one with me at a time, I shower an imense amount of attention on them then. I also whisper when I talk to them, so that the other's don't hear.

They are all well fed, loved and cared for and they will have to learn to share you with each other. Right now Basil is needy - kitten type needy, just like Noah was. Aren't they just like children?

It will be fine. You will adjust and so will they. It takes time.

Good luck!
