How might annual feeding frequency change for older Ball Pythons beyond 18 or 20 years?

Shifting from monthly to every three to four weeks.

As Ball Pythons enter their senior years, typically considered beyond 18 or 20 years of age, their metabolic rate and general activity level can subtly decrease, necessitating adjustments in care routines beyond standard guidelines. One notable shift observed by expert stewards concerns dietary needs. While younger adults might adhere to a strict monthly feeding schedule, older individuals may require sustenance less frequently, sometimes needing meals only every three to four weeks. Owners must pay close attention to monitoring the snake's body weight and condition rather than rigidly adhering to the calendar date to ensure they meet the nutritional needs of their aging companion.
