My friend outdoor cat has did this twice with the same result, kitten dies. This is her second litter and she dropped 3 kittens. The cat was moved to a plastic recycle bin for birthing the kittens and just like last year one kitten was not suckling and the mom did not seems to care or miss her. The neighbor took this kitten in ( they are old and have nothing todo and had free time ) and tried to provide milk via a small baby dropper and bottle with no luck. THe also left a light on for warmth. It died about 30hrs after birth.
