When I bought my first snake I started keeping a journal of every feeding, shed, and any changes like moves to new tanks, bedding changes, introduction of new chemical products. It's become a good routine for me and I'm sure it will come in handy if any issues arise. If not, it's pretty cool to know how many mice my snakes have eaten in their time with me. My Corn Snake just had his 74th feeding, and my new BP is at his 3rd feeding with me. Does anyone here keep journals for their animals? Any other details that you make a note of?
