You might like to get a playmate around her own age (a little younger or older wouldn't matter, I think) for Jasmin before she grows up- it's a lot easier for them to bond before they're a year old, in my experience (unless the adult cat happens to grow into the nurturing type- which you can't really tell ahead of time). Also, I have a theory (backed by quite a few cats) that female cats are much more likely to accept female kittens as friends.

Even when I've raised female & male kittens together they tend to be standoffish as adults, but whenever female kittens have grown up together they've stayed close and cuddly/grooming friendly.
