The first picture below is Nicky (who we thought was male), mainly due to his longer tail.
This next is Crush, our female (smaller tail)
Here they are together (you can see the Nicky's nails on one foot - by the intake screen)
And here Nicky is the one on top.....
I guess I was focusing on Nicky's tail to determine sex - maybe it's just that Crush's tail is really small.
Crush is approx 7.5" and Nicky is 5 3/4".
Two girls is just fine. I'm not in any position to add more little one's and I would have a hard time giving them up.
Thanks for your help.
