I got four baby bunnies almost two weeks ago, theyre 9 weeks old. We are working on litter training but they keep peeing on the wood floors in their xpen. Rabbit pee ruins the wood floors and theres 4 spots that are ruined. So I got those foam mats that children use as floor play mats then covered it with a canvas drop cloth. They stuck their butt on the edge of the xpen and the pee soaked through the canvas onto the floor and my mom is now threatening to put them outside or get rid of them. I love my bunnies and I dont want that to happen. What can I do to keep the wood floors safe so I dont have to lose my bunnies?
