When you bring your rabbit into your home, you will need to sacrifice a few things. Just like if you bring home a new puppy or kitten, the bunny will need to be kept safe and cannot go untrained.
Before you bring your new bunny home, get the bunny's living space ready. The rabbit will not be able to roam your house right away. It will feel much safer in its own cage.
The rabbit's "living space" is the place you will send or put your rabbit when you need to leave it unsupervised. This is where it's litter box should be, as well as its feeding dishes and bed (if any). You can use a cage as the living space or make a section off your living room or kitchen with baby gates.
Good things to keep in the rabbit's living space are the rabbit's feeding dishes and water bottle, litter box, chew toys (baby rattles, toilet paper tubes, untreated wood blocks, small pieces of newspaper), and a place for the bunny to hide in or use as a playground. Your rabbit won't need a bed, but having a comfy place for the bunny to rest is always a good idea.
The best place to leave your rabbit for long periods of time, unsupervised, is a place where it will be contained in a cage or on a hardwood surface, in case of accidents. Rabbits can also chew and dig at carpet and it can be poisonous if ingested.
Getting down on the rabbit's level is the best way to see what the rabbit can chew, dig at or destroy that be dangerous.
Make sure there are no wires or electrical cords in the rabbit's living space. Rabbits like to chew, and they can electrocute and kill themselves if they allowed to reach these.
Also keep all plastic bags and plastic items out of the rabbit's living space. Rabbits can play with baby toys (like rattles), that are plastic, as long as the rabbit can't actually eat or bite off any parts. Plastic can clog the intestines and cause problems.
Lots of plants are poisonous to your rabbit so make sure it won't have any access to a houseplant when it is in its living space.
Keep your belongings away from the rabbit, if you don't want them ruined, chewed on or utterly destroyed.
Once you bring your rabbit home, it will appreciate the nice, new living space you have prepared for it. Try to complete bunny's new home before bringing the bunny into your family, so it doesn't have to go through too much stress once it gets home.
Whenever you let your rabbit out of its living space, make sure you never leave it unsupervised unless you completely bunny proof every part of the house the rabbit has access too. Keep in mind, also, that until the rabbit is FULLY potty-trained, small accidents are not uncommon.
