Oh, I'm so sorry to hear of the loss of your dear little hermie I sounds like you provide them with a most wonderful life and home setting. I live on the ocean, and only know the life of hermies in their natural habitat and don't know what they require in a home setting. I can't imagine there was anything you could have done differently. As has been said, life in captivity must add extra challenges. But no doubt, you provided a very caring and loving home to your hermie. Please don't blame yourself Rest in peace little one. You were very loved.
