Angelsoo,
always take the nursing mum together with the kittens and put them in a 1-tier cage for protection. It is always better. Other female cats may accept other cats' kittens at a certain time but it does not mean they will accept kittens at a later time.

I have personally seen this happen. One mother cat I picked up had accepted 2 sets of orphans, one set after another, but had later swiped fiercely at another set of orphans introduced. She had simply refused to accept them. Things can change.

It is always a great blessing to be able to pick up the mom cat together with its kittens because then, it is so very easy to care for them. All you have to do is to give the best kitten kibble to feed the mum cat all that she can eat and she will be the milk bottle for them. She will also clean them up and give them the love and affection needed for healthy emotional growth, and later teach them the important lessons in life they need for their social adaptations and survival.

I find a vast difference between kittens raised with a mother cat and orphans raised by the human hand. The skills acquired is tremendous, especially the survival part (i.e how to recognise danger and escape).

June,
make sure you secure the mother cat well ASAP for the sake of the kittens. You will be in great trouble if something happens and the mother cat disappears leaving you with just the young kittens. ASAP!
