These babies are adorable. Neither of my babies are brown spotted. There are other colours that are also Savannahs, the brown spotted is just the commonest. The black spotted (melanistic) kitten is male, and the colour pointed kitten is female. These lovely babies are overdue their own loving homes. They are really sweet babies, lots of energy, and need playing with before feeding, especially bedtime feed so they will sleep through the night.
The colour point came into the breed with the first mating of a Serval, it mated a Siamese, so the pointed gene is set in stone, and they are acknowledged as genuine Savannahs. The babies re well grown, and should be on the larger size when adult. They have been raised on good food, and I don't recommend anything you can buy in the supermarket if you want them to grow well.
I have both parents and they can be seen, although my boy isn't used to strangers so may be a bit shy.
They have been raised with dogs, and now snuggle with my rescued Staffordshire Bull Terrier. He is so gentle with them.
