I used to years ago but I can't seem to find that template I used back then so I'm going to have somebody who's really good in excel make me another template. I was using a program but it's just a little too much info that I won't use and a few other things that I'm not set on about it. I'll only keep track of feed, shed, weight, weight of food, how much food and stuff like that. I won't keep track of pee or poo because I have 3 of my snakes in the same tanks together.
