* Hygiene: Keeping the vent area clean is essential for the rabbit's health.
* Health issues: Any unusual discharge, swelling, or odor around the vent could indicate a health problem and require veterinary attention.
* Mating: The vent is the site for mating.
* Litter box training: Understanding where the vent is can help you choose an appropriate location for the litter box.
It's always best to consult a veterinarian for any questions or concerns about your rabbit's health.
