My 11 year old python isn't pooping that often. I was always told to wait until they poop before feeding them again, is this always the case? For example, it has been 10 days since she last ate and is due to eat again. I always fed her every 10 days since she was about 6 years old. Her activity level is very low.

However, she still has never refused a meal. Can this indicate malnutrition, not being fed enough?
