Cat moving kittens

I have a blue point siamese who had a litter of kittens five days ago. (Dont worry, I am a CFA registered breeder.) My problem is Sarah keeps moving her kittens to dangerous locations. Two nights ago I woke up to the kittens crying. I saw Sarah carry a kitten to the top bunk of my brothers bunkbed. I took the kitten and put it back into the box. Then last night she took a kitten and laid it beside me in bed.
Her box that she is in is in a very private location. (My bedroom closet.) She had the kittens in this box. After the birth I changed all the towels, and put sheets in the box instead.
Does anyone have any ideas on how I can make her leave the kittens in the box?

Meghan,

Many breeders employ the use of a queening cage for exactly this reason. I use an extra-large dog crate. My queen is used to it (I leave it set up and open for her to explore prior to delivery) and goes into it without a problem. She delivers in there and when the babies are old enough to do more than that funny little "commando crawl", I can shut the door and protect them.

You could employ the use of such an enclosure for your queen and her babies too - only shut the door and let your girl out for trips to her litter and food bowls several times a day. I might add that you should watch her carefully while the door is open so she doesn't move the babies to inappropriate places.

My cat just moved her litter too. She did it after I changed the kittens bedding. I guess she didn't like it. I spent two hours searching the house until I found them. I was worried to death that they weren't in a warm enough place. I finally found them in a room we rarely use in a very small area. It certainly wasn't big enough for her to nurse them there. It was nice and warm so I moved the items around a little to make the area a bit bigger, then I put her blanket back under the kittens.

She did her best to not give away their location but once I found them and fixed the area she laid down to nurse. I stayed with her a while and rubbed her head and then I left. She seems to be happy now, so I am not going to try and move them back to the closet. I figure if she wants them there then I will leave them, at least it is warm and safe.

It sure scared me for a while though.
