Lizzy's 4th Litter

On 11th August, Lizzy gave birth to 3 pups after I have mixed her with Ben. The next day, I found the fourth babies, dead in the cage. I guess it's a result of a failed delivery and maybe there are a few more unborn pups because Lizzy's body still looks quite big. The same day, one of the three pups died, leaving 2 only till this day. The images of them below taken on the fourth day after birth.
