I would recommend never feeding 3 mice per meal- many snakes (including rat snakes) will stuff themselves if allowed, because their instincts tell them to eat when they can get food- it's not guaranteed or reliable in the wild, unlike when they're our pets. (length? always harder to judge from pics- a yardstick next to her in the ground pic would be great)
She's on the "well-fed" side - no danger of starvation- and would benefit from being fed every 10+ days from now on- especially if being fed 2 mice. I wouldn't feed 2 if feeding weekly ever- one per week would be better, but I'd still recommend every 10 days, not weekly: maybe one feeding of one mouse, the next one give 2, alternating. Meals don't have to be equal all the time, & you can back off gradually so she doesn't accuse you of neglect, lol.
Noodle's a pretty gal, & really growing up- she looks healthy, but just don't over-do the food. Adult rat snakes (& 2 years is an adult) are best fed every 10-14 days. Wild snakes have a chance to 'work it off', not so our home-buddies.
Thanks for the update!
