Dexter...

Dexter's bio says he's a "F6 SBT Savannah Cat," which means he's a sixth-generation hybrid feline as defined by Stud Book Tradition (which deems these cats as purebred). There are six generations bred from a wild African Serval, with three generations as Savannah to Savannah to ensure they have the affectionate, docile temperament like other domestic cats. As big as Dexter is, these kitties can grow to be 25 pounds or more, like their wild counterparts! It's really cool that they keep the tradition of spotted or striped fur like their Serval ancestors! Though an F6 is legal in most states, that's not always the case, and with the F1 or F2, they're a lot closer to an actual Serval and less likely to be as domestic as a cutie like Dexter. Whatever he's titled as, he's one handsome mini tiger!
