I absolutely agree with Karen, the problem is not the rabbit being outside at all, the problem is the raccoons. When they are determined enough they can get through just about anything....a combination lock is not going to keep raccoons out of the bunny cage. Also as Karen says rabbits can die of fright and I've seen it happen under much less stressful circumstances than a bunny being threatened by a predator.

THAT'S where the concern is from most of us who have replied to your message...we want what's best for your bunny. And when you put a concern on POTD you have to be prepared to take the responses. No one is intentionally cruel or mean, just very concerned about the welfare of your bunny.

Kingrattus has a good point....baby bunnies are almost impossible to litter box train, while adults will often train themselves to use a litter box. Also when the bunny is spayed/neutered their urine odor is less strong, so then it's merely a matter of keeping the litter boxes clean. You might mention that to you parents.
