I do not think you should get them if they are going to be in a cage while you are working and then let out to free range in your room while you are home. I just googled, them and they are pretty common where I live, however even if I wanted one, I wouldn't get one let alone two, because of how big they get. I saw one next to a dog, and it was the same size!!! The reason why I would never get one, and do not think you should get one is because of the space you would need to give them and can't. I feel like my apartment is too small for one... my whole apartment. Considering you are just going to have them in a small area while you work and then your room when your there I do not think you should get them because that would be unfair to them. Now as I said I feel my apartment is to small for one let alone too. Maybe I just like to give my animals a lot of room... I don't know, but I wouldn't put them in anything smaller than something that was *****12 ft wide by 12ft.*** I am sure people have them in much smaller spaces than that however, I would never let my cat not have full run of the house and since these rabbits get bigger than cats... I saw two of them that were bigger than a dog, why would you even consider keeping them in anything smaller than your house.
**** Now that I think of it, I would only put one in there. Looking at my living room, as a guide I wouldn't put them in anything smaller. My living room is 15ft wide by 25ft. I know that is a lot of space, but considering these things can get as big as dogs, and you want two of them, it really isn't as big as it sounds. Again I am sure people keep several rabbits in much smaller spaces than I would, however, I would never keep a rabbit let alone two of the kind you want to get in anything smaller than 12ft by 12ft.
Ps. This is just my opinion, I don't have that much experience with rabbits. I do know though, that when my cousin lived with us, we let her rabbit have free run of our living room, and it was a really small rabbit, like half the size of my cat and my cat is only 8 pounds. Hopefully I don't offend anyone with my thoughts.
