If you're finding that your rabbits are eating paper, there are a few things you can do to help stop this behavior. First, take a look at what type of paper they're eating. If it's something like toilet paper or napkins, try to switch to a different brand that doesn't have as much scent. You can also try putting the paper up high where they can't reach it.
If your rabbits are still determined to eat paper, one option is to provide them with an alternative source of food such as hay or pellets. You can also try giving them chew toys to gnaw on instead. Whatever you do, make sure that you supervise your rabbits closely so that they don't end up swallowing any large pieces of paper which could cause blockages in their digestive system.
