Hi there, I have a very curious and rambunctious cat who often likes to go into the bun’s enclosures. The issue I see for you now is that your bunny is very young, so is more vulnerable to being hurt and more fearful.
With my cat, when the bunny gets scared, he gets more predatory. Remember, play for cats is predatory. They tend to test things out to see what they will do, so if the bun runs they can start to see them as prey. When they buns stand up to him (either aren’t scared, or fully chase him off), he leaves them alone.
For now, since your bunny is very young, I would minimize their interactions. When your cat goes near the cage, squirt her with a water bottle. Don’t let your cat be around the bunny unsupervised (even when the bun is caged), and for a bit, don’t let the bun exercise when the cat is in the same room.
This will be a bit cumbersome at first, but you want to avoid a situation where the bun learns to fear the cat and thus initiates it as a game of “cat and mouse” for your cat. When you do start allowing them to be around each other, have your water bottle handy and squirt your cat anytime she does anything remotely threatening to the bun (including the swatting thing, I know exactly what you’re talking about).
I have a suspicion that once your bun gets older, she will stand up to the cat and you won’t have a problem. I’ve also noticed that once cats learn that the rabbits are WAY faster than they are, they kind of give up trying to chase them. My bunnies currently are definitely the boss of my cat. He will sometimes go in their condos to try to sleep in their beds LOL but never tries anything predatory with them. But I did have a very scared foster at one point, and that was a different story.
I’ve also found it really helps to distract the cat with a more appropriate toy while the buns are exercising, and don’t use any toys that remotely resemble a bunny. I usually bust out my wand toy (that has a feathered bird type lure on the end) to exercise my cat if he’s acting a bit too rambunctious around the bunnies. Keeping your cat stimulated and exercised will reduce her interest in your bunny.
Hope that helps!
