Yeah he's part savannah, but only an F6, so the bloodline from a pure savannah is diluted. That cat is an absolute nightmare, he is so funny, but when he wants to he can be brutal as well. Savannahs are expert bird catchers and that's what his favourite pastime is. He'll fetch 2 or 3 home a week. They're not scared of water one bit and to prove that he fetched a 10" koi carp home from a neighbours garden pond about 2 years ago. I had to reimburse my neighbour for that and he's since put a net on his pond. He'll also jump in the shower with you, something that freaks me out bearing in mind he tends to dive on anything wriggly and worm like

.
He fetches mice, rats and rabbits home quite regularly but astonishingly he brought home a baby fox only a month or so ago. I was in bed, it was late one night and my missus was still up. She heard a whelping in the garden. When she went out the cat dropped the squealing young fox and it ran off!! Lucky fox.
He climbs in open windows of neighbours houses scaring them half to death. He also went through a phase when he was really young of pinching clothes off washing lines. But the worse thing he used to do was perch on the top of an open door stalking and when you came through the door you'd be wearing a savage cat as a hat! He'd just dive on your head and I ended up with some really bad scratches on my face once. Thankfully he doesn't do that anymore.
I could go on and on. All I can say is that anyone with a savannah, where the bloodline is less diluted and closer to the pure savannah than ours, I feel you're pain. Lol.
