I just use google docs at this point, but I only have 12 snakes. Copied the basic idea from one I found somewhere (can't remember who or where, though). Basic info only. Feedings, weights, poops, sheds, pairings when appropriate.
The Clean column is being removed. No real need to track it and I'm bad about tracking that one particular item anyways.
For me with this number of snakes, this works for now.
