This is not a f1 or a f2 Savannah cat. However They been breed to have the appearance of an exotic early generation.
This silver Savannah kittens have rich coats and nice smuggy dark noses with perfect spots
The males do tend to get bigger than females but every Savannah cat varies. I seen bigger females and vise verse.
I will take the kittens to vet to get fvrcp vaccine and dewormed plus fiv and felv tested. Which are negative.
