As you might be able to tell from reading this blog, The Bunniverse is a pet rabbit blog. In other words we don't discuss meat rabbits, breeding, etc. But I'd like to think that this blog doesn't feel judgmental because if you're a breeder or a rabbit farmer you still own rabbits and a rabbit is a rabbit is a rabbit. Just because you don't view them as pets doesn't mean they're any different from my bunnies or the bunnies sitting in shelters. I talked to one man (he worked at my shelter!) who tried to justify meat rabbits by saying,"We didn't think of them as pets."
So where am I going with this? RWAF (Rabbit Welfare Association and Fund) in Europe has redone their informational pamphlets. This is what they'll look like: http://rabbitwelfare.co.uk/pdfs/RWAbrochuremaster.pdf They cost €1 and I'd strongly suggest buying some, which you can do at http://www.bunnybazaar.com/RBLBKLT/Books-and-Free-Leaflets/Hop-To-It--A-comprehensive-guide-to-rabbit-care
If you live anywhere else in the world The House Rabbit Society (http://www.rabbit.org/index.html) is a very good resource. You can order pamphlets from them and the site itself has a lot of good info.
So what does this all have to do with the first paragraph? My point is that you don't have to have house rabbits to read these pamphlets. Every rabbit needs social interaction, proper food, and shelter. These sort of things are non-negotiable, I can think of no reason why they shouldn't have these those basic fundamentals.
If you know someone who is keeping a rabbit in a less then habitable situation, I'd suggest giving them a booklet or pointing them to a good website. Most cases of rabbits in neglect stem from lack of information, not cruelty. And if you're feeling inspired how about buying some of those booklets and writing a company that tests on rabbits? There is a lot you can do with these pamphlets- take advantage of it.
And once you're done find a good book, your bunny, and curl up on the nearest comfy surface!
