This cat is twice the size of it's littermates, so believing that a breeder of 25 years plus knows, I will expect that size and be pleased if it doesn't reach that much. My Bengal was declawed before I adopted it and it NEVER bites. Years ago, we adopted a kitten that had survived drinking antifreeze, but was blind as a result. It subsequently was declawed front only and it never bit. I doubt seriously this Serval will ever feel the need to defend itself, but natural behavior is for them to roll on their backs and kick with their rear feet. This would not be an aggressive or protective act, it would simply be instinctive behavior. I will check with the Serval group. When googling, I did not see that group, but did see the Savannahs, so I thought I'd give it a try. Thank you one and all, I will continue my search elsewhere.
