Will Cats Steal Other Cats Kittens?

I had 3 cats give birth within 2 weeks of each other. One of the mothers got into her sisters box of kittens and started to feed them. When the sister came back into the room she realised she couldnt get into her box as her sister was in there, so she got into the other box with the older litter and became mum to them. My 3rd mum cat kept taking the ginger kittens from both litters and hiding them behind the settee, along wit her 2 ginger kittens. This has left my asking myself, can cats tell the difference between different colours? It make me wonder as they say cats cannot see in colour.

I had two  mother cats that had kittens with in the same week and the cat that had kittens before took the kittens  from the cat that had not had kittens before.

Just to clarify... Cat's can see in colour,
the only shade they have difficulty with is blue.

Oh yes!!! I found a cat *I named her Kookoo, for good reason, I guess* When she had her kittens, 4 total, she went around the neighborhood stealing kittens. She wound up with 23!!!!!!!!! I found a no-kill shelter that was looking for a mother like her. The last I heard she was still taking any kitten they gave her. She was the best mother I'd ever seen!!!
