She doesnt seem to be mourning the ones that passed. The one that is still alive eats like crazy lol but i do worry everytime i have a litter born that there not getting enough so i give formula fir extra nutrients. And this one is chubby already lol it sucks good too i noticed the other two didnt try at all.
Its very possible these two were goners, whatever you did. Happens often enough. And its wellknow its easier to save healthy orphans and sickly weak kittens. But with hindsight we can tell, its these two you should put on all your energy on. Perhaps even take them from momma, if momma wasnt very apparently continuing to take care of them....
Sometimes, not seldom, such weak ones whom would die off in nature, can be saved by their human owner into a healthy home cat.
Of course, a serious breeder prob wouldnt use such a one in their breeding programme, they would be sold as pet cat.
Shes taking care of the one thats still alive, and she was taking carr of the other two but they just wouldnt stay warm, i kept trying. I buried them in my backyard.
