Well done Treacle, you are a lovely Mum and know what you are doing. I hope you let your foster Mum get some sleep in the early hours.
I think it is three live ones so far. Sadly Socks had a stillbirth, as she had not even tried to lick it, it was a big one though compared to the other kittens. Makes me wonder if she was mated twice? The colour of the stillborn one was mostly black.
The others are mostly black like their Mum with a little white on them.
