Maybe Mom can't jump up and out with the larger kittens?

Could you place a box, or ladder, down into the window well to reuduce the distance she has to jump? Might try that for a while this evening.

If she doesn't use the "stairs" by dark; then KittenNap the lil guys and try you hand at Kitten Feeding .

Good Luck to you and the Kitties .
