I’m sorry that your parents aren’t open to the idea of a better habitat. I think something I’ve always done when trying to convince someone to do a certain thing is write down a list of pros or positives for the idea you’re promoting, in this case — a better area for her!! I can speak to a few positives about ex-pens!! both of my boys each have there own ex pen area set up, they share one wall, but have plenty of room! they are great for many reasons:
– quite easy to rearrange and move
– if you have some kind of easily cleanable floor underneath than that makes cleaning a breeze! for me it’s just a sweep and a spot wipe!! (they’re on tile but also have soft things like fleece pieces / seagrass mats
– relatively cheap, if you order online it’s even better. just make sure that if you get a shorter size, you have something you can put over it (i just use an old bed sheet!)
– and lastly, this would obviously be a better area for rain to live in, I’m not sure how much they know about rabbits but we all know that the most space is the best!! there’s lots of options when it comes to pens, much more than if you just have a simple store-bought cage.
i’m not sure what kind of cage you have, but I’ve found I like pen setups much better! If you have any other questions I would love to try and help!! based of my experiences of course. I do hope your parents come around!! be sure to keep us updated.
also!! you can add even more floor space to ex pens by adding wood shelves! that’s what we have for our buns!! again I hope this helps you in some way!! don’t be embarrassed to literally take a list of written down points when you talk to them, i’ve done it!! it just makes you more prepared and shows them this is a big deal, because they probably don’t see that right now!!
