My Rabbit - the eating machine!

I was instructed not to give too much food to my rabbit to eat. Then one day, I found that my friend's rabbit was so heavy and full of "flesh" under the fur. So, I figured that my rabbit is under nourished.

So, we thought that rabbit should be smart enough to know when to stop eating. Therefore, we gave him a big bunch of kang kong stalk and root. To our surprise, he finished munching the whole lot of kang kong!
We also realised that he is getting smarter. If the door to the cage is not fully latched, he knows how to open the door.

So, one day, when we returned from work, we found the stalk of orchid on the dinning table was reduced to this! Who did it? Of course it was the rabbit! He ate...

the whole stalk of this orchid!
So, he is eating anything... rice, orchid, etc.
