Yesterday I met someone who used to have a basenji. A tri that reached the beautiful age of 17. He was telling very passionate about it 
I would think that some Basenjis have a stronger hunting instinct than others. I have had Basenjis innocently free roaming among sheep and others that would immdiately go in to kill.
Exactly. When we had only Jazzy, she lived in relative peace with our cats.
They weren't friends or friendly, but she didn't chase them much and when she did it was without much enthusiasm.
Then we got Keoki and everything changed. I know I've talked about him before – he broke three baby gates in his efforts to get at our cats. We've tried various things to bring them together peacefully -- crating the dog, crating the cats, slow introductions, etc. -- and nothing has been remotely helpful. It's been three years.
So, now the cats live upstairs -- which is bigger than the downstairs and where the kids spend the bulk of their afternoons and all night -- and the Basenjis live downstairs.
I should add, the cats have never been the problem. They have both lived in peace and friendship -- sleeping together etc -- with our dogs in the past. Neither one had ever been chased by a dog, Until Jazz, whom as I said did okay with them, but they were never friends as they'd always been with our other dogs.
And Keoki....forget about it.
