Oh, what a cute tux girl!

I hope time will help with Stormy! You can use Feliway to make her feel more comfortable with each other.

I also had to introduce a female kitten (Lily) to a female three year old (Luna) and the first days I thought I had made a big mistake! But within a week, they became good friends, and now Luna has even adopted Lily as her baby and lets her suckle.

It's been a breakthrough in their friendship when I rubbed Lily with a wet towel with which I had rubbed Luna before. Actually I did it to help them cool off during the horrible heatwave we had this summer, but I guess smelling her own scent on Lily helped Luna to accept her. Maybe you can try something like that, too!
