House training a pet rabbit
All rabbits are territorial. We can use that 'territorialness' to our own advantage by setting up an area in the home which is HIS with a litter tray, ceramic bowls, hidey house, cat tunnels.
Initially surround it with wire playpen panels 90cm high with a gate. (See photo below of a rabbit playpen)
Once he is using his tray perfectly, the gate can be open.
If he stops using his litter tray eg going in another room, return him to the playpen for a few days until he is again correctly using his tray.
Rufus and Coco have a wonderful white rabbit litter tray pet litter which absorbs everything. It is available in Coles or Woolworths or on the manufacturers' website.
You should put edible hay over the rabbit pet litter.
You should feed hay daily just an extra big handful on one side of the litter tray.
This encourages the rabbit to use the litter tray.
Having your bunny in your home with your encourages interaction and ensures that your pet will remain a member of your family forever. The opposite to this is a dreaded cage in the backyard which then just becomes a chore that is only visited to clean or feed:(
