I see many people saying "as long as they don't lose significant weight" when replying to someone worried about their snake not eating. But how much weight does a ball python need to be losing in order for it to be considered significant? For a snake of, for example, 1,190 grams how much weight loss would be worrying?
It's really not about a set number it's about overall health, and good body proportion depending on whether the animal is male or female.
Just like the opposite is true too when people ask how much their animal should weigh at a certain age, not about number either.
