Bunnies outdoors tend to live 3-5 years, but indoor bunnies can live 10-13 years, so make sure you are prepared for that kind of situation (I really had to think about it with my turtles, I have 50 year with those assholes! XD)
Overall I hope I was able to be somewhat helpful XD feel free to ask me any questions! also here's my bunnies!
They are very smart creatures and can be trained to do many things. My first bunny came to me litter trained, and by that I mean he could roam around the house whenever, but would hop back to his cage to use the potty. They like to be active and play, so make sure to keep them with toys and rearrange the cage every once in a while. They are also really expressive, minus what others may say. http://www.toomanybunnies.com/unders...y-languag.html
That link has some things on bunny behavior and what it may mean.
They don't eat carrots as much as we are led to believe.
Not all veggies are ok, nor are all weeds from flowerbeds (in case you do gardening you can cut down on waste by giving your bunny the dandelions and horsetails, though the horsetails make them pee alot, just like asparagus) The onion family of foods are harmful to them, for example.
For a first pet? Maybe.
For a child no, for a teenager/young adult yes.
They are not very difficult to keep, but just like most animals the initial setup is the most costly. Cage, bedding, food, toys, salt licks, and maybe a playpen for it.
While they are generally cage-kept, they do require exercise (preferably outside in a small yard or playpen in a grass area)
Feeding wise they are pretty easy. You can buy packaged food for them, and it is highly encouraged to add in some real fruits and veggies. BUT They actually eat mostly hay then anything. I think hay is supposed to make up 60-70% of their diet?
I have had some people say rabbits can smell gross. And yes they can, if you do not properly clean the cage often. If they are indoors, I suggest once a week change of bedding. Outside is every 2 weeks or so, you would find yourself adding bedding more often then changing out because they tend to toss is out of the cage quite often.
