Yes, she sent me pictures of the mom & dad. The mom is an f2, tall, skinny, big ears. The dad is an f6, larger than most cats, still big ears but not like what you see when you look up pictures of Savannah cats. Thank you for the information about lineage! I guess I just thought because I had seen f6 & f7's with really big ears, I thought f3's would definitely have them. And the differences between the sisters is a lot, so I just wasn't sure.
Several years ago, there was a breeder (can't remember who) who had what she called a rainbow litter -- snow, gold, red, chocolate -- and it was quite a surprise to her. Despite best efforts to produce to the breed standard, total control of genes is up to mother nature. I've seen siblings from the same litter that look so different I've wondered if an alien cat somehow got in with the queen LOL.
My first SV is an F2 with Bengal somewhere in his lineage. He as great deep black spots, the coveted black nose and tiniest ears and feet. He looks like a frankenkitty made of spare parts. His brother got all the good genes
My other F2 is a silver F2A (father is an Egyptian Mau). He has a rough coat, unimpressive ears and is long and lean.
My F6 is small -- 11 lbs -- but has a beautiful puffy nose and large cup-shaped ears. Of the 3, he is the closest to serval in body type but his spots aren't that great.
My F1 is spectacular. John Popp, who is a member here has his brother from the same litter and they are quite a bit different from each other. John also has a brother from a different litter (same parents) and he is closer in looks to my F1.
One thing they all have in common is the savannah personality -- fun, loving, trouble making, pain in the butts.
