Please keep on giving Ponzi timothy hay....many of my bunnies didn't like hay at first but it is essential to their diet and eventually they did start to eat it....now it's often the first thing they eat when fed, except of course if carrots and/or parsley are given out at the same time.

You might try getting Ponzi a puppy pen from the pet store...here in the states, they are made of metal, and have about 8 sections so that it sets up in an octagon shape. The smallest one will give a bunny about 5-6 feet of space to play in and will keep him off your couch. He can spend a lot of time inside this pen as they have a lot more room in them than any cage will.... He should still be let out twice a day for an hour or two of exercise and to stretch his legs..... It sounds like he is a baby and during their first year baby bunnies have boundless energy and drive most people crazy....But neutering and age will calm him down. Good luck with Ponzi!
