My family just got a dog who intently hunts my cat

I need some help. I've had my cat for a while, and due to some circumstances with my crazy uncle, now have his sweetheart of a pitbull. Its the first day of having her

She already snapped at one, smaller dog at my normal uncles house before she got here, but I wasnt there so I dont know how exactly it happened, only that she's (little dog) timid and I think they said that could've done something for her?

Knowing this, I put my cat in a kennel we've had for dog situations before so she could come in and not immediately go hunt, then I introduced them at the kennel, then let my cat out. He's not very fond of the dog, as he's used to dogs shoving their faces into his, but I noticed that she was staring at him over intently, and unless I kept calling her name, she wouldn't stop. Wouldn't drool, but I still figured its predator behavior, which

And then I call my cat closer to pet him while I'm holding her leash and harness where she is. This is the closest the two have gotten, being just about face-to-face, and turns out I was right and she saw him as prey. He ran, no injuries or even contact, but she went crazy after him so I immediately kept her from her bone and put her in the same kennel (I dont really like using kennels, I actually hope we can keep them both out of the kennel entirely, but its the only way to reprimand her that I know, that isn't hitting which, hell no I'm not gonna do)

I'm wondering a few things, but mainly: is this even feasible? She's spent a lot of time with quite frankly, a bipolar drug addict, though she's sweet as all hell to humans, but with her being grown enough to be a mother by now I'm afraid of it being too late, and that she may always just see cats as food

There was one interaction that she paid no mind to him, when my mom got home and she was getting excited to meet whoever just came into the house. My cat was outside my room door, blocking the path, and when she got close, he went to scratch her cheek and kinda did? But she was focused on the noises downstairs so she hardly even registered him being there. They were as close to eachother as when she snapped at him later
