I had been using a cream on my Desert Tortoise to help with any needed vitamins while he slept during Hibernation. I would put the cream on before putting him down for the winter and again when he came out of hibernation in the spring. For some reason the company that made this no longer offers it. This cream was to revitalize dry, brittle or cracked shells and skin. Anyone have any ideas on what can be used as a replacement for the cream that is no longer on the marker.
