When you take your rabbit to the vet, you will need to put him in a carrier. When you get a new carrier, you must let him get used to it before taking him to the vet in it. Going to the vet can be a stressful experience in itself, so the carrier your rabbit is traveling in should not add unnecessary stress.
To get your bunny used to his carrier, you should bring it out during play time. You can put something familiar to the rabbit in the carrier so he feels comfortable going in and checking it out. If your rabbit does not go in his carrier on his own, you should put a treat in it. Once your rabbit goes in and eats his treat, you should add more treats to reward him for being in his carrier.
After a couple days of your rabbit eating treats out of his carrier, you should shut the door when he is comfortably inside. Leave him in the carrier for 1 minute, and gradually increase the time throughout the next few days until you are at about 20 minutes. Your rabbit should be comfortable in his cage, and this is the best way to ensure he does not associate his carrier with stress.
There are many rabbit carriers to choose from. You can choose a plastic-and-wire carrier that people typically associate with airline crates. An example of this type of carrier is the Double Door Deluxe Pet Kennel. This carrier is great because there is the usual side door, but there is also a door on top so it is easy to get your rabbit in the carrier. My rabbit likes another airline approved carrier called the Air Lines Deluxe Pet Carrier, pictured above. It is lightweight so it is easy for you to carry around. Plus, there is a soft lining bottom layer that can be easily removed and cleaned. There is even a seatbelt strap so your rabbit will be safe during car rides to the vet! When you are not using it, you can fold it flat for easy storage.
No matter what type of carrier you choose, do not skimp on your carrier because you will be using it for a long time!
