Kittens should not be given away before they are 8 weeks old, so she still has 2 months.
The question may be how she can check people: the people from whom we got our cats asked many questions and both of them came to visit us after some weeks. I think that's ok -both parts should take it serious.

As to the patterns: they will stay. And after they open their eyes they will be cuter and funnier every day. Enjoy it
