So my rabbit Coconut is 6 years old and not neutered. We got him at a pretty old age so it wasn’t recommended that we neuter him. So we didn’t. We also have two bunnies that he discovered, even though they are fixed, they still get territorial. We separated them and now Coconut escaped his room and found the bunnies. Since he isn’t neutered, he likes to bother them. Coconut is in a room with no doors, that is blocked off by a 4 ft box and 2 ft box on the side. This is just until his pen arrives, so we are scared that he is able to jump over that. We don’t want to get another pen cause they are EXPENSIVE. Any recommendations on how to keep him inside the pen? Also neutering isn’t an option right now.
