That's information I'll take into consideration when building future racks. I don't remember when exactly when I found the chart but when I got my first ball python I was searching google to see if there was any kind of feeding chart similar to what people use for clubrids. Even though I bought a care book written by the southerlands from TSK, I personally like to do a vast amount of research because what works for 1 person might not work for the next. Ball pythons with all their quirks and shyness are fascinating animals.
