Rabbits are tedious groomers, just like cats. They rarely need a bath unless they have diarrhea or get into something sticky that mats the fur. A rabbit is usually fearful of water, and wet baths can cause great stress. Try a dry bath to clean your bunny if he is not accustomed to a wet bath. If your rabbit has urinary incontinence or diarrhea, take him to your veterinary for a diagnosis and treatment.
Dry Bath for Bunnies
Make a comfortable place for your rabbit to lie on the floor, using soft, fluffy bath towels. Lay your bunny on his back and talk to him soothingly while petting him to reassure him everything is OK.
Shake baby cornstarch powder on any messy areas of your bunny, including near his rear end. Put on plastic gloves and work the powder into his fur down to the skin level while talking to him and petting him.
Comb the powder out of his hair gently with a fine-tooth comb, such as a flea comb. Try to keep the excess powder on the towel as you comb out your rabbit.
Give your rabbit a nice treat for being patient, and toss the bath towels in the laundry.
Wet Bath for Bunnies
Place a bath towel in the bottom of your kitchen sink. Fill the sink with lukewarm water about 2 1/2 inches deep.
Pour about a tablespoon of hypoallergenic, non-medicated shampoo into the bath water and swish it to mix it into the water.
Lower your bunny's rear end into the water while holding him underneath his middle, keeping his front legs out of the water. Wash the messy areas of your rabbit with the soapy water.
Rinse your bunny well with clean water to remove all soap residue from his hair and skin. Towel dry your rabbit as much as possible.
Blow-dry your rabbit with the dryer set on the low heat and low airflow settings. Do not direct the air at his face, and hold the dryer at least 12 inches from his face. Check the air's temperature often.
