Huge bunny knocks kitten off of box, tries to stalk back

Our 8 month old kitten and 10 month old bunny are having a bit of fun playing around and sneaking up on each other. The cat is all trying to ambush her but waits too long and then ends up ducking herself, the silly wuss :P Not weird that she’s cautious tho, cause the bunny may be slightly lower, he weighs like twice as much and isn’t afraid to knock the cat over, and the cat remembers well :P Female kitten called Mouse, male bunny called Ketjap. In the cage is another male bunny called Sambal, age 3.
