Bonding
When you first get your new friend home, talk to them often so they can learn your voice. If you have a shirt or towel you don't need, you can put it in their cage for them to get your scent (it also gives them a comfy spot to lay).
Approach your rabbit cage slowly, especially in the beginning.
Give them small treats to help them get used to you. Who doesn't like friends who bring them food!
Getting down to their level makes it less stressful for them. You can also pet your rabbit to calm him/her down.
When you're ready to hold them, say down on their level, scoop him/her up by placing a hand under the torso and pull your bunny close to your body.
Continue to support their hindquarters to keep your bunny safe and speak to them quietly. They may squirm, if so continue to hold them securely to you.
Put him/her back in the cage the same way your lifted them out. They may respond with a thump but it's nothing personal.
Spend time with your rabbit every day and you will quickly gain a new best friend!
