The biggest still are the black girls, at 149 and 160g and the blue girl at 137g. I reckon 2 -3 days there will be a mass doubling of their birth weights.
One black girl had an eye open yesterday surprising me when I picked her up to weigh her with her a cheeky little wink! It always surprises me when their eyes open. The other 2 females had followed suit this morning, strangely all with naughty one-eye open winks! (I just had another look now and I was seen - with both eyes now fully open - and even got the tiniest little meow! Missed it when taking the photo below! Sooooo cute.
Blue girl is quite the sleepy-head, she zonks out in the evening and, when jostled by a sibling or her mum, has the biggest yawn.
