Weird Momma Cat Behaviour?

My cat had 4 beautiful babies two days ago. I have another cat who also queened the same night, so we put them in separate rooms to keep either of the mommies from doing something rash.

Anyway, Loki, who was the cat in my room, did fine all day with her kittens in my dark, quiet bedroom, but when I came in to bed and was playing video games, she suddenly moved one of her kittens (the largest one; I'm not sure if it matters) under my bed. He was squeaking frantically so I dove underneath and took him out, putting him back in their box. I was afraid that Loki would hurt him for some reason, so I took the whole box back into my mum's room where she could keep an eye on them.

I read that when queens do this it's either to separate a sick kitten, because she can't care for all of them, or because they're too cold/too light/etc. She moved them under my bed, where the other cats like to go when they come into my room, so I'm thinking that she just thought it was too cold for her, but I'm not really an expert so I'm not sure.

I just want a little reassurance so that I can take the proper measures. I put her in a warmer, and I hope, more comfortable environment to see if it helps. If she does it again to the same kitten I'm going to try and adopt him to our other nursing momma, and see if that works. And if she moves a different one or more than one... I'm stumped! Any help, please?

Ok, they do this to black bears and imagine it would work with the cats. First, put a very,very little bit of Vick's Vaporub on the tip of cats nose. Please don't use more than a tiny smear that is no larger than one quarter of the eraser on a pencil. You can do this while they are sleeping if you are careful. Now, as soon as you can get a chance, put the same amount of vick's anywhere on the kittens, (not near any thing like the eyes or rectum or mouth please). Now, since cats, like most animals identify their offspring by scent and since it should take about a half day for the Vick's to wear off of the mommies you can do this. Put all the kittens together and let the mommies each check out the kittens separately. The mommas will think that they are all her kittens. Then you can let both mommas in the room and they will each share the momma duties of feeding, washing and whatever of all the cats. Hope this helps you.

A night course I took on wild animal behaviour. This was how they convinced a momma bear to (adopt) an abandoned cub.
And... my mother one had two cats have kittens simultaneously and she did this and all 13 kittens suddenly had two mommas.

I wouldnt remove the kitten or adopt it out, the momma cat most likely doent feel comfortable where she had her kittens. Mom cats always try to move there kittens (experience ) If you were playing video games, sometimes noise and bright lights will make the momma cat want to move her kittens aswell. The mom cat wont hurt the kittens intentionally the kittens may sound like there in pain from the sqeeking but there not unless she is noitceably hurting them. Just see whats most comfotable for her. My cat has her kittens in a box in my room under my dresser where it is dark. Maybe also try a box with cover over the top and the whole in the front. If she is used to being under your bed and tried to move them there it might be in best nature for her box to be put under there to reduce stress. Also the other kittens in the house by the other mommma cat would be giving off smells and maybe confusing her make sure you keep them apart so she doesnt stress. hope this helps.

I would be contacting the vet about it. The kitten may be ill and needing medical care. They will all need shots and de-worming and as soon as they are all weaned the queens must be spayed. All of the kittens will have to be spayed/neutered when the vet tells you it's safe to do so. The vet should be very involved to help you out with the different stages and problems that can occur with Queens and their litters.
