Ahhhhh, I can't stop looking at the pics. Justice is just the sweetest, most precious tiny little fur ball. I just love her and you can see that Morph is just wonderful with her. It makes me want my very own mastidane/kitten duo.
You'll have to keep us all happy with lots of pics of your new addition.
BTW, our youngest son fell in love with Blackberry (black kitty) last fall and that's how she joined our family too. He is wonderful with her, except for the little hair trim that he gave her a couple of months ago.
He didn't hurt her at all (thank goodness) but was seriously warned and he hasn't done it again. They absolutely adore each other. I'm betting that it'll be the same with Mason & Justice. (Modified to add: hopefully without the hair trim
) Enjoy!
