Too cute!

And yes, the rabbit chased the cat. I experienced the exact same thing with my little dwarf rabbit, Walnut and my orange tabby, Tangie. Normally Tangie was a hyper, ultra brave little explorer cat...until Walnut came out for exercise and visiting. Then that cat would run and hide. I had them both on the bed at one time and Tangie backed away so much from the very curious Walnut that she fell off the bed.

I like both your cat and bunny, very nice markings.
