heh, that explains it, my rabbits were also hyper active when they were so young, when there sat on the couch they always climbed up my shoulder and layed down behind my head, they kinda liked heights back then, they could even jump onto there own shelter outside. i reckon that is about a meter high.
I really like those rabbits, We had two lop ears and we made the big mistake of feeding them lots or carrots, We had the steam pro on stand by all the time. Our vet said carrots upset their bowel system and it's not a good idea to feed them .
