I think you are right - whatever killed Momma cat is also taking her little ones. How heartbreaking for you! I wish I could say somthing to make you feel better, but I know that you are heartbroken right now.

But, by making this sacrifice (of your emotions and love) you have made sure that they passed on to the Rainbow Bridge feeling warm and secure, and LOVED. So they will now be re-united with their Mommy and their littermates, and will be playing at the bridge at watching over you and your brood. They must have been very special kittens, to be called to the bridge so early, and you are such a special person to care for them during their short time here.
