Introducing a new rabbit into an environment with another bunny should be carried out gradually, ideally at least a month after they have been sterilised. Before the rabbits meet for the first time, you can gently rub both of their noses and body with a strong-smelling substance. This helps to disguise the individual smells of each rabbit.
Some things to use include strong smelling herbs like parsley, mint or basil otherwise vanilla or lavender essence also works well. This can also be rubbed on the fur of the rabbits too if need be.
It is important always to introduce new rabbits in a neutral territory, ideally somewhere where both rabbits have never been before. This might be a laundry or bathroom or a certain safe spot in the garden.
Decorate this area with lots of interesting things like boxes/tunnels and yummy food items. Creating a fun and enriching environment will hopefully keep the rabbit’s interest on these items instead of each other.
The initial introduction should only be for 5 – 10 minutes at a time, but repeated regularly throughout the day. As they begin to accept each other the length of time can be extended. Bonding rabbits is a long process and often can take several weeks.
