In Israel, and probably most of the world, most house rabbits are given to children, who keep them in tiny cages (cheap) and forget about them after a month. The tragedy of the house rabbit is its low price. The costs of having a healthy and happy rabbit are enormous compared to the price you pay for the animal at the pet shop. For comparison, ferrets are treated much better simply because they cost 150-300$ and not 10-20$.
The other extreme of caring for a house rabbit is letting it run loose in the house, eat fresh vegetables with scientifically balanced dry mix and giving it unlimited attention. Not so easy!
I remember the day I came home from work. Stella came running to get her head rubbing fix. I picked her up and sat in front of the TV. Something was wrong. The sound system was shredded. I decided to surf the web. The modem supply cord was cut in two places.
Since that day, we kept Stella in a back room. Her projects included digging holes in the wall (new instructable: how to dig a hole in the wall) and shredding anything we absent mindedly decide to put in that room, including two very expensive mattresses.
Finally, I saw on the web a caging system that looked cool. It was a labyrinth of wire mesh cages assembled together to make a relatively large playing area for rabbits. Problem: it is not available in Israel. So, after finishing a basic wood working class, I decided to build a cage. The goal was to give Stella a big enough playing ground without compromising our apartment's free area and without letting her cause any more damage.
Step 1: Buying the Bars
Lately, hardware stores in Jerusalem show a range of wire mesh based storage solutions. I based my cage on two 1.2m-by-0.5m shelves (App. 4ft by 1.5ft). A shelf makes an excellent door because it has an optimal grid and usually L shaped, which makes it easier to mount on the wood construction. I found my shelves in "Ace Hardware". But I guess one can get them almost everywhere. I think that wire mesh shelves are more popular in America than in Israel. Here we have less built in closets. The simple grey bars make better cages than the PVC coated ones. Remember, rabbits chew.
Since the cage doors' measurements are the anchor of this project, go shopping before sitting down to the drawing board.
