I have two house buns, I could just be lucky but I've never had any major problems with chewing, so far. It takes a lot of time and patience to help train them not to go where they shouldn't. If they start nibbling a chair leg for instance, then in a loud, firm deeper voice, just say 'NO', they will always try again and again so you may have to do this a few times, after a couple of tries and they're still doing it, try clapping your hands together as well as saying 'NO' but don't lunge towards them or tap/poke them. They should realise after a while that they aren't meant to go there but be careful, if your back is turned for a second they may have another try, so all free range time should be supervised. Be prepared to spend a lot of time on the floor, and try and play with her as much as you can so you can keep her distracted. After 8 months I can comfortably leave Peanut out of her cage if I want to pop to the shops and I no longer worry now, so it's all worth the effort.
Edit/added: Peanut is deaf and I still managed to train her, I think me clapping my hands near her worked to let her know she shouldn't do something even though at the time I didn't realise she was deaf.
There are other things of course that you can do to bunny proof, cover wires up with tubing, even if you've hidden them she'll probably find them, use clear sticky back plastic to protect some things if you can, it could be useful on skirting and some people put it on the corners of their carpet as the buns can't chew or scratch because the plastic is too slippery for them to get any grip. You could get clear perspex as well which you can also use to cover and protect certain areas. You could get some large willow matts, phone books, carboard tunnels to keep her busy. Don't leave anything of value on the floor or within reach if you don't want anything nibbled at. Block off any gaps where you don't want them to go, I use anything that will fit, DVDs, books, old bits of wood, the wii fit that I never use has come in very handy for the gap down the side of the sofa :lol: You can also get wire mesh panels from Wickes that you can connect together to fence some areas off, your house will never look the same again I'm afraid :lol:
As with litter training, most buns will always wee in one place so wherever that will be, is where you should place the litter tray, if it's in a really inconvenient place then put a newspaper there and then put the soiled newspaper in a litter tray near by and hope that she starts using that instead, you may have to do this a few times too, you may also have to put up with a few wee stains on your carpet/floor but it's easily cleaned up. Peanut decided that to the side of my kitchen door was where she wanted her toilet to be :roll: so that is now where it is :lol: I'm sure there are a few other tricks and tips but I can't think of them right now and I've already waffled on enough. Good luck and I hope it goes ok
