Nigel granted me an audience.
He's a Savannah (part African Serval) and chirps and yodels. No meows.
Raw chicken legs with bone are his primary diet.
Best not to get near him when he is feeding.
Can jump from floor to top of fridge and leap from there 10-12ft to my shoulder, usually uninvited. Fully clawed, as are all 3 of my cats.
The marks do not buff out!
