I want to get a bangal kitten but it's only 7 weeks old?

I got my kitten at 8 or 9 weeks. If the person you want to get her from sucks and doesn't know what they're doing, get that kitten outta there is my opinion. I'm glad you don't want to breed her. Ask the owner you're getting her from what he's been feeding her, etc. Just kitten food and water. Solid food in a couple weeks. She'll be alright. By the way, that's a gorgeous cat.
