Cat gave birth to a kitten and then abandoned it, We do our best to find and locate a foster mother

Cat gave birth to a kitten and threw it away. We are trying to help and find a foster mother.

In the morning we saw that a wild cat was giving birth under our shed
One kitten showed no signs of life and the cat did not lick it.

I know that if a street cat throws out a kitten after birth, she will not come to him.
I decided to get a kitten, but it was impossible to do it with our hands, the cat is aggressive.
