Our huts are made with lightweight denim. While they are considerably safer than the fuzzy huts that are associated with crop impaction issues, caution should still be used. Because ours are not fuzzy, there is a less likely chance that a bird will pick and chew on them. We add extra support inside to ensure these will last. 
CARE INSTRUCTIONS:
Do NOT put these in the washing machine. Simply wipe clean with a damp cloth.
