Ferrets stink primarily because of their biology, specifically due to scent glands all over their body that produce a musky odor. The strongest odor comes from their anal glands, which they use for communication and territorial marking. This musky smell is a natural part of being a ferret and is normal regardless of their age or health. While most ferrets in the United States have their anal glands removed (a procedure called descenting) during spaying or neutering to reduce the smell, this does not eliminate their natural odor entirely. Additionally, the smell can be intensified by their environment, such as when their bedding or cages are not kept clean or if their feces produce a strong odor. Other factors that can influence ferret odor include diet, health conditions like infections or dental disease, and if the ferret is not groomed regularly. The normal musky scent is distinct but manageable with proper care, cleanliness, and veterinary attention when unusual smells arise. In summary, ferret stink comes from:

• Musky secretions from scent glands all over their body.
• Potent odors from the anal glands used for communication.
• Environmental factors, including cage cleanliness and diet.
• Health issues that may cause abnormal odors.

Removing anal glands (descenting), spaying/neutering, keeping their living area clean, feeding a quality diet, and grooming regularly can help reduce but not completely eliminate ferret odor.
