Aw, grown up pics!!! They have grown into very beautiful girls, Popcorn looks just like my first ever cat Lucy. Thank you so much for posting these, its brilliant to see how well they are getting on!
Does look like Peanut is laughing in that first pic, lol!
As to the size differences, Peanut was a slightly chunkier kitten and I think her fur is a bit thicker too which probably accounts for some of it. My girls are different in size too for sisters, Amber is a pig and a fair bit larger than Chilli!
