thank you candacebell...
..no I haven't any picture of WW in winter coat, because both male and female didn't turn white last winter (the female for a while, seemed to start becoming paler, but at the end she didn't...)
...you can see some sapphire among the babies, in all the litters till now (4)there was at least one (the maximum was 3 on 7)
...the babies seem to be subject to color coat changing in the first 3 weeks...a sapphire (apparently) turned to normal during the 3rd week, strange, isn't it?
bye bye
