As the title says... What's your method?
I use 2 different ways to document everything. I use iHerp and my own excel spreadsheet that I printed off and keep in a binder and fill it out with a pen. The iHerp is for convenience and the records in the notebook are just in case something ever happens to iHerp. Plus, I just like keeping paper records.
I have a page for each of my snakes, and I just have to fill out the date and what they ate, what they refused, if they defecated, if they shed, their weight, or any other notes or info. Here is a screenshot of my sheet for Paxton, my ghost boy: http://i49.tinypic.com/3168zno.png
I would love to see screenshots of what you all use!
