Grooming

Brushing
Rabbits love to be clean and will constantly lick themselves like cats. They can get hairballs if they ingest too much fur. Unlike cats, rabbits cannot vomit. If hairballs are allowed to form, they can become tangled masses of fur and food and will consequently block their digestion. Regular brushing along with plenty of hay helps to reduce this danger. You may use a slicker brush or bristle brush. Rabbits should be brushed 1-2 times a week or as needed.

In the case that your bunny does not like brushes at all, you may also try dampening your hands with water and wipe them over your rabbit to catch all the loose fur. Rub your hands to get the fur off, and rinse and repeat. You can also try using a damp hand towel instead, if you do not like the feeling of fur clinging to your hand.

During the severe molting season when your rabbit grows a new coat of fur, you can also just use your fingers to gently tug and pluck out his loose fur. It should come out easily without too much force and should not bother the rabbit much.

Trimming Nails
Rabbits should have their nails trimmed every month or two. Most vets, shelters, and rescue centers that deal with rabbits will offer this service for a small fee. If you would like to trim your rabbit's nails yourself, you may use small animal clippers. Be careful to only cut the nail and not the quick (the blood inside the nail). The quick should be easily located on a white or light-colored nail. If you do accidentally hit the quick, the rabbit's nail will start bleeding profusely. Use a little styptic powder, cornstarch, or baking flour with a moistened cotton swab or cotton ball to the area and apply moderate pressure for 5 to 10 seconds to stop the bleeding. If your bunny has black nails, shining a bright flashlight from underneath the nail will help you locate the quick.

Cleaning Scent Glands
Rabbits have scent glands around their vent and anus. Sometimes rabbits will be unable to groom the area and will cause odor and possible infections. The discharge should look like wax with a very strong odor. Use a cotton swab that has been dipped in warm water, diluted hydrogen peroxide, or mineral oil and gently swipe out any residue that might be present in the scent glands. This should be done as necessary, which is usually around once a month.

Bathing
Rabbits do not require any baths and should never be entirely submersed in water unless it is an emergency. It may stress the rabbit to the point of shock or heart failure, and if not properly dried, the rabbit may get hypothermia and die. If cleaning is necessary, try using baby cornstarch powder first to spot clean their fur.

In the instance that your rabbit does get soaked to the skin, it is imperative to try to towel dry the rabbit to the best of your ability and use a hair dryer or heating pad to keep the bunny warm to finish off drying. Use a hair dryer only on the lowest heat setting because rabbit skin is very delicate and can be easily burned.

Trimming Fur
In general, there is no reason to ever need to trim the fur on your rabbit unless he is a long-haired breed. Brushing, not trimming, will rid the bunny of any loose fur. Short and normal-furred rabbits only need their fur trimmed or shaved for a medical procedure or if there is matted fur that cannot be teased apart.

In the case that you do decide to help trim your long-haired rabbit (e.g. Angora, Jersey Wooley), there is no need to trim the fur super short. Also, be very careful with the scissors and use blunt round-tipped ones. Rabbit skin is very thin and delicate and is easily torn. Do not cut your rabbit's whiskers because they are important sensory tools that help a rabbit navigate in front of them (a blind spot). However, in the accidental case that you do, do not worry; the whiskers will grow back.

Difficulties and Solutions
Sometimes, rabbits can be very difficult when you are trying to groom them. The following is a list of solutions if you run into any difficulties.

Bunny Burrito
If you are having problems with squirming when trying to trim nails, you can try to use a bunny burrito. The basic idea is to set him on a towel and wrap it around him snugly, then hold onto him and only expose the parts you want to work with. One good video on trimming nails with a bunny burrito can be found here.
