Making spreadsheet for my BP, help me w/ ideas

So I'm in the process of making a spreadsheet to keep track of my BPs weight, feeding, sheds, etc. Please list some things you think should also go on it. Here is what I already have:

Dated:

BP Weight, Prey Item Fed, Prey Weight, Shed dates, Bowel movement dates

Non-dated:

Total Amt Fed, Average Food Weight, Total Weight Gained, all setup to update automatically as data is entered

Any other ideas or input would be appreciated. One thing I was thinking was to maybe add dated thumbnail pics, to have a kind of visual log, but I think they might take up too much room. I like things neat and organized.

Thanks!

Mods, feel free to delete. I found a similar thread with a bunch of ideas in the husbandry section

just use DEGEI. Its free and easy.

I don't like using Windows, I have a Mac and can boot Windows, but I prefer only to use Windows for games. Also, I only have one BP as of right now so a simple spreadsheet is enough for me. Maybe in the future when I get more animals I will look into this software.
