How do you know if a cat misses her kittens?

Well, I know they are only 6 weeks old, we haven't homed them yet. But Mika is separated from them, shes down at our house now, but how do you know if momma misses her babies? Cause Mika is looking for them, but can't seem to find them anywhere!! Because we didn't bring them down here, and they are down at my grandma's but will have a foster mom, called Smokie. They really aren't nursing on mom anymore. Only very occasionally. This is too soon to take mom away though. But, Mika has destryoed my grandma's dryer thingy that connects it to get outdoors. And my grandma wasn't going to have it. So she wanted her gone today. So here she is. But, ya. Well, sorry if I have upset anyone, I was just wondering what to do.. Thank you for reading! P.S. Mika isn't pregnant!!!

Is she trying to get out because she is in heat? It is very possible at 6 weeks after the birth. Can you get her spayed? Or maybe bring her kittens to your house just for another two or three weeks - they really should be together, and of course she will miss them, as they will her. They are rather too old to accept a foster mom just like that.

No, my mom said no more cats, and I have to rehome MIka... But I figured out, Mika wanted me.... She was trying to get out to find me... And she wasn't happy down at my grandma's. I know this for a fact.
