First off it's ok to go get her fixed now even if she still has milk, the last mommy cat I had fixed was still nursing, but the kittens where 8 weeks old and eating on there own so it was not a problem. I was glad I did she was in heat right after that so if god forbid she ever got out I could have had more kittens.

Even after she was fixed the kittens still nursed off her for months later, they got no milk but at least had their mommys love. They where almost as big as their mom and still nursing, it was so funny looking. I think they still be trying if mom didn't stop them......I think she finally got feed up with them trying.


Call your vet and I'm sure he will tell you it's fine to bring her in now. And if she lets them nurse don't worry about it, nature will take it course, mom will get tired of it and stop it in her own time.
