I get a lot of emails describing the same scenario: Bunnikins has taken to hopping on the sofa and peeing on it. It’s a frustrating situation and one that has happened in our household as well. I remember after the third time it happened with Cosette a few years back, I had picked her up and put her in her cage. (She still had a cage back then although it was always open.) I closed the cage door and closed the kitchen door where the cage was located. But even in the other room I could hear her thrashing around in the cage trying to break free. For a rabbit who detests being picked up and despises even more being cooped up in a cage, this was the greatest insult. I felt bad locking her in – and I did let her out again after an hour - but after that time, she never peed on the sofa again.
I later came across an incredibly useful article on the House Rabbit Society website which helps shed light on this behavior and suggests ways to train your rabbit. The article is called “FAQ: Training,” and under the heading “Behavior motivated by social structure,” it delves specifically into the peeing on the couch problem.
Anyone who is experiencing this issue should read the article. The entire article is actually very enlightening as well- covering various issues that most bunny owners will come across at some point.
