Walk a Savannah cat - a dog in cat's body

Actually the price varies greatly. You can find f1's for less than $3,000. And it also seems to matter the definition of F1, F2, to the breeder in question. Maybe someone knows for sure how the terms are supposed to be defined in Savannah/cat hybrid breeding, but an F2 could be F1 x F1, F1 x serval, F1 x domestic, etc... And what would a F1 x F3 be? An F4? An F2? The F1's seem to be pretty consistent, serval x domestic cat, but even then, it depends on the "domestic" cat used in creating the hybrid. All this seems to add up in the charged price.
