So. Since Adopting Candyfloss (who is much whiter and less pink lately) my rabbits have slowly progressed downwards in terms of their pooping and peeing outside of the litterbox. Before, they were all perfect. Now....not so much. It's marking. The three don't get along remotely. Erik sorta tolerates Candyfloss, but Sofie hates her with an utter passion. So this is what they do: When Candyfloss is out, she goes poop and pee all around their cage. When Erik/Sofie are out, they go poop and pee all around her cage. They can't be put in separated rooms as we have one huge HEPA filter that allows both my and my bf's allergies to tolerate having the rabbits inside. I know someone will suggest getting another filter, but you can shell out the $300 for a decent one. My question is- how can I stop some of this? I can tolerate turds but the peeing on the carpet is beginning to become a huge problem. I started using Nature's Miracle, which has eliminated the pee smell for them and so Erik and Candy have been peeing considerably less, but they're still doing it. If I can't get them to stop, how can I direct this behavior to something that is more beneficial (re: sanitary) for human but still allows bunnehs to get out their territory marking?? Suggestions??? Help...?
