I'm a bunny person! I've had pet bunnies off and on for over 30 years and have kept up on the current recommendations regarding how to keep bunnies happy and healthy.
In the past, bunnies were kept in hutches outside. This is no longer recommended for a variety of reasons. They don't tolerate temperature changes well. Heat is especially deadly to them but they don't do well in extreme cold either. There are many predators in an outdoor environment including dogs, cats, racoons, possums, even squirrels. Even if these animals can't get to your rabbit or wouldn't hurt him even if they did, the rabbit doesn't know that. They scare very easily and can have heart attacks just by seeing another animal and feeling threatened. There are also a variety of diseases a rabbit can catch just by being outside, mostly brought by insects. For these reasons (and more) rabbits should always be kept indoors.
We also know now that rabbits are very social creatures. They are much happier when they are able to live as part of the family. They quickly become depressed when left for much of the time on their own. They need more socialization than they are able to get when left outside and visited briefly by humans. They also tend to be friendlier and more trusting of humans when living indoors. Our two rabbits' cages are in our entry way between the front door and the kitchen. We also pass them anytime we're coming or going from the stairway. Everyone talks to them as they pass by and we all stop to pet them several times a day. A healthy, indoor rabbit can live anywhere from 10-15 years. Outdoor rabbits generally won't live that long.
We've also learned that rabbits must be spayed and neutered for better behavior and for their health. It's now known that 85% of female rabbits will suffer from reproductive cancer by the age of 5 if they are not spayed. That's a slow and painful death that can be easily prevented. Spaying and neutering will calm down a teenaged rabbit and keep the males from biting and spraying when they get overly excited. If you get a pet rabbit, be sure to have it spayed or neutered around 5-6 months of age.
Rabbits can easily be litterbox trained and most will do it on their own. They are very neat animals and will tend to do their business in one corner of their cage. As soon as you determine where they like to do it, just put a litterbox in that corner. Bunny will be happy to use it and keep his cage clean. Always look for a rabbit-approved litter. Cat litter (especially clay-based) is not OK for rabbits. Check with a pet store for a paper-based pellet-type litter.
We learned about diet the hard way with one of our rabbits several years ago. We were feeding him alfalfa pellets and alfalfa hay and he developed a kidney stone from too much calcium. We learned that rabbits should eat timothy pellets and timothy hay for better health. There are several safe fruits and vegetables that can also be fed in small quantities. A good website is
www.houserabbitsociety.org. They have a section on nutrition that lists safe foods for rabbits to eat. Rabbit play time should always be indoors. There are too many poisionous plants outside and the aforementioned predators. Also, I hear so many stories about rabbits that esaped under fences and through open gates. We confine our rabbits to play in our family room and kitchen. They come out one at a time and the rooms are bunny-proofed (no exposed cords, etc.).
The absolute best place to get a bunny is through your local humane society or rabbit rescue agency (the House Rabbit Society mentioned above lists several). These bunnies have all been checked by vets. Those that are old enough will be spayed or neutered before you're allowed to take them home. They've also been socialized and had their personalities evaluated. The agency will be able to help you choose a rabbit that will fit into your household the best. I would advise against buying a baby bunny from a pet store. First, there are many, many wonderful rabbits at shelters that face euthanasia if they're not adopted. Pet store bunnies tend to come from over-bred females and many face health problems later in life. Plus, an older rabbit has already established his personality and you will know what to expect from him. Teenage rabbits (5 - 9 months) get very weird. They get an influx of hormones and many start biting and chewing. Spaying and neutering will reduce this behavior but many people get fed up with teenage bunny behavior and end up giving the bunny away.
I know this is long, but I hope it's helped. I love bunnies and think they make wonderful pets. However, it's important to understand that they do take just as much work as dogs and cats. If you're willing to keep a bunny indoors and make a 10-15 year commitment, go and find the right bunny for you!
