I can understand where you're coming from. My parents were like that, too. Let me ask you a few questions:
- What kind of litter do you use?
- How often do you clean the litterbox?
- Is your bunny spayed/neutered?
- How old is your bunny?
The answers will let us be able to help you with your difficulties, and probably make the situation more bearable for you and for your parents. I know, it's difficult being under someone else's roof and having to listen to their opinions about things, especially when it is ultimately their decision. I've never agreed to parents holding that aspect over their kids' heads (my mother did that), but at the same time, they're your parents and you don't have much option at this point, other than to try to compromise a bit so that all involved can relax and be happier.
I would recommend NOT getting into arguments about it with them anymore, but instead doing everything you can to cut costs for your bun, and making the room you live in much more bearable for them.
As far as litter, wood pellet litter (which you can find REALLY cheap at a feed store for horses...it's called horse stall wood pellet bedding) is really the best litter there is, both for absorption and odor control. My bunnies each have two litterboxes (which are small kitty litter boxes, rectangular), which I clean out every other day (and would clean out everyday if they only had one box). If your bunny isn't spayed/neutered, I would recommend asking them to get a piece of indoor/outdoor carpeting, or some such, for your bunny to be on while he/she's out, so that if she "goes" outside her litterbox, it's not directly on the flooring they have. Also, bring her litterbox out when she's out, and if she pees outside her box, soak up the pee with a papertowel, and put the papertowel (and her) in her litterbox. She'll soon get the idea. You just have to be sure to be REALLY stubborn about it, and if she insists on peeing outside the box, third time's a charm, and put her back in her cage. Believe me, she'll learn. That's how I taught Maisie...and she's VERY stubborn. I don't have to even bring her litterbox out of the cage anymore when I let her out...she hops back into the cage to "go" when she needs to.
As far as the wallpaper...I'm not terribly experienced in keeping bunnies from doing things like that. Maisie is really good about listening (Flower's still learning, but doesn't really do anything wrong). Maisie can tell by the way I say her name that I'm not happy, and stops doing what she's doing wrong. Clapping and saying your bun's name sternly helps. This is what I did with Maisie. Ooh...one thing I've read is if you take Ivory soap (barsoap, not liquid) and rub it on the places you don't want your bunny to chew, they don't like it, and won't chew it. Give that a shot. Surely your parents won't object to buying cheap ol' Ivory. It shouldn't discolor the wallpaper, and from what I've heard, really works well.
Over all, just try to meet your parents in the middle a bit with this, okay? I know it's not very nice the way they're acting, but you have to find some way to compromise until you are old enough, and have the financial means, to move out and have your own space. I know it's hard...like I said, I've very much been there. Just know that here you have people that care, and we're here for you.
Let us know how things work out, ok?
