I chart sheds, poops, if I see them, when I feed them, what size mouse, if I produced it, whether it was live or f/t, if I put vitamins and calcium on it or not, and whether they ate it forward or backward. I don't write it all out, but have abbreviations for everything. One feeding will read: 1 f/t fuzzy, s, m, f, which means that they ate 1 f/t fuzzy, with supplements, and it was mine, and that he ate it forwards. I also weigh them when they shed and record that. Also I have recorded events like regurge (only one so far, thank God), striking for the first time, trip to the vet, being popped, stuff like that. Of course, I am a total nerd with no life, so no one really has to be THAT specific. I just like to keep track of things. And I'm a bit crazy about it sometimes. :crazy02:
