Prof. Henry Webster, Ph.D.Preventing mold in your rabbit's hay racks will save your pet from potentially deadly toxins. Rabbits are prone to these toxins, which develop in hay that absorbs moisture during storage. Position your hay racks in unexpected places, ensuring they have a minimum airflow space of 2-3 inches (5-7.5 cm) in all directions. Keep racks away from moisture sources and check regularly to ensure they are not retaining moisture, especially in humid environments.
Airflow Management
- Maintain 2-3 inch gap between rack and walls
- Choose open wire designs instead of solid backs
- Position racks where air circulates freely
Moisture Control
- Check hay dryness before filling racks
- Use dehumidifiers in humid environments
- Avoid placing racks near water sources
Daily Monitoring
- Inspect bottom layers for dampness each morning
- Feel hay texture for unusual warmth indicating fermentation
- Sniff for musty odors developing before visible mold
Design Selection
- Never use racks with solid backs trapping moisture
- Select racks with elevated bases preventing ground contact
- Prioritize materials like stainless steel resisting moisture
Good air circulation prevents mold. It's the stagnant, moist air that allows mold spores to multiply. The good open rack design also allows for air circulation to dry damp hay. Sufficient circulation is essential. Be sure to keep your racks away from the wall or corner, and ensure that nothing impedes the airflow around the feeder.
The selection of materials has a big impact on moisture retention. The best material for resisting mold is stainless steel due to the non-porous surface. Plastic has microscopic pores that hold moisture. Wood holds humidity like a sponge. For the best option in terms of safety and durability, use powder-coated metal.
Year-round mold prevention requires strategies tailored to the local climate. During humid summers, place moisture-absorbing crystals near the racks to help keep them dry. During wet climate months, cover outdoor enclosures completely with waterproof roof panels. In winter, heating the interior can dry the air too much, which more easily leads to mold growth; therefore, maintaining adequate humidity is recommended. Continuously assess methods by season.
React promptly to signs of mold in hay. Dispose of any hay that has the slightest odor of mustiness. Scrub the racks in a vinegar solution, and dry completely in the sun. Replace with hay from fresh sealed bags. When in doubt, toss it and get more. Never offer suspect hay to rabbits.
