It's a hard decision to make really - you would really need to choose the incoming kitten very carefully or else you could make the situation so much worse. Not all cats want the companionship of other cats - a lot of them are quite happy to be only cats - it's just us folks who like to see everyone "paired up" so to speak. You would need to have a very laid back kitten - one who is neither too confident or quite as timid as your present cat. I wish you the best of luck.

BTW have you tried some Feliway plug in diffusers around the house - these may help her feel calmer or maybe some honeysuckle spray?
