My experience has been the same as Kelly's. I don't know whether it's just a fluke, but my girls are just horny girls. They do their job - and no more (and sometimes less!). There's no lingering goodbyes - they don't pine over their kitties. Most actively avoid them at nine weeks old (and one of them at only five weeks, as I said earlier).
This has been the same for our Bengals (which is by far the majority of our cats), our Russian Blues and our Abys.
Perhaps it's something in our water.
We have to be careful not to anthromorphosise. Cats aren't people. I haven't seen a mum get stressed out by separation yet. Perhaps it's just the breeds I have here, but they're all perfect mums.. and perfect women for our studs. Once the kittens are independant they don't want to know.
