Respiratory Issues in Hedgehogs

Respiratory infections, including pneumonia, are a significant health concern for African Pygmy Hedgehogs. Their respiratory systems are sensitive, and an infection can become serious very quickly. These illnesses are often linked to the hedgehog's environment, making proper husbandry a critical factor in prevention.

Causes of Respiratory Infections

Respiratory infections in hedgehogs are typically bacterial. The infection can be primary, or it can arise secondary to other issues that have weakened the hedgehog or irritated its respiratory tract.

• Improper Bedding: Dusty beddings can be inhaled, causing irritation that can lead to infection. Aromatic wood shavings like cedar and non-kiln-dried pine are toxic and should never be used.
• Poor Cage Hygiene: A dirty, damp cage can harbor bacteria and mold. High levels of ammonia from urine are also highly irritating to the lungs.
• Aspiration: This is a serious risk. If a hedgehog inhales water while drinking from a bowl, or inhales food or medication that is being syringe-fed incorrectly, it can lead to a severe and often fatal aspiration pneumonia.
• Other Illnesses: A hedgehog that is already battling another health issue, such as cancer or Wobbly Hedgehog Syndrome (WHS), will have a weakened immune system and be more susceptible to infections.

Signs of a Respiratory Problem

It is vital for owners to recognize the signs of respiratory distress in a hedgehog.

• Sneezing, Coughing, or Wheezing.
• Nasal Discharge: Any wetness or bubbling from the nose.
• "Clicking" Sounds: A clicking or rattling sound when breathing is a common sign of fluid or inflammation in the airways.
• Labored Breathing: You may see the hedgehog's sides heaving with the effort of breathing.
• Lethargy: A decrease in normal activity, such as not running on their wheel.
• Loss of Appetite: This is a common sign of many illnesses in hedgehogs.

Diagnosis and Treatment

A hedgehog showing any signs of breathing difficulty needs to see a veterinarian immediately.

• Diagnosis: The veterinarian will listen to the hedgehog's chest with a stethoscope. A chest x-ray is the most important diagnostic tool to confirm pneumonia.
• Treatment: Treatment will involve a course of hedgehog-safe antibiotics. For more severe cases, hospitalization may be required for supportive care, including oxygen therapy, nebulization (medicated steam treatment), and fluids.

Prevention

• Use Safe, Low-Dust Bedding: Paper-based beddings or fleece liners are excellent choices. If using wood shavings, stick to kiln-dried pine or aspen.
• Keep the Cage Clean and Dry: Regular and thorough cage cleaning is essential to prevent the buildup of ammonia and bacteria.
• Use a Water Bottle: While some hedgehogs use bowls, a water bottle can help to prevent accidental inhalation of water, reducing the risk of aspiration.
• Maintain a Stable Temperature: Avoid drafts and keep the hedgehog's enclosure in a warm, stable temperature range (typically 74-78°F or 23-26°C).
• Proper Syringe-Feeding Technique: If you ever need to syringe-feed your hedgehog medication or food, do so slowly, with the syringe aimed to the side of the mouth, to prevent aspiration.

By providing a clean, safe, and appropriate environment, you can minimize the risks and help your hedgehog stay healthy.
