Cleaning out scent glands
Rabbits have a scent gland either side of their anus. The scent gland needs cleaning out as the scent is a liquid that can clog up the gland. Its a yucky stinky job, but it needs to be done. To clean the scent glands out, get a cotton bud and wet it with warm water. You may need to get someone to help you hold the rabbit upside down securely. Gently swab at the scent glands until the discharge comes off. If you have any trouble doing this, ask your vet to do it for you.
