Beautiful. Do they love each other? I've been thinking of another rescue kitty but not sure how that will work since she is such an established Queen of her territory ;) Your bigger kitty looks like maybe some Maine Coon in there because of stature and size - unless just the angle of the lens.
They are still in the getting to know you stage and I heard that it takes some time to establish a bond between the kitties. I think that it is unique based on their individual personalities and Satoshi is extremely energetic and playful.
They look like duplicates of each other....even their pose. So cute :) I'm sure they will be the best of friends.
I completely agree and hope that they will be inseparable soon.
