ball python feeding

hi everyone i have had my ball python for about 4 years. i got here when she was a hatchling and started feeding her pinkies then adult mice then small rats and now i have been feeding here medium rats for about 6 months. i use to feed her every 2 weeks most of her life and now i figured since she has gotten bigger and she is eating larger meals maybe it would be better to feed her every 3 to 4 weeks. Is this a good idea or should be eating sooner then that? she is close to 4 ft long and little over 1 inch diameter on the thickest part of her body. i have gotten bitten by her 3 times since i owned her. but i have noticed that lately she is a bit more aggressive then usual and was wondering if this is because i changed her feeding pattern? if anyone has some help or suggestions please write back thanks.:salute:

I wouldent wait 3-4 week periods i'd say feed her every two weeks at the max but maybe make her meals back to adult mice to small rats, its all about what the snake likes.

no she eats the medium size rats fine but she seems more aggressive lately and im wondering if its because im waiting to long to feed her.

I feed my snakes every 7 days....if I were to wait longer....I think they would figure a way out of their enclosure and eat me....lol. No my snakes have a little calendar in their enclosure....like clock work every Saturday they are on the hunt.

Most everyone that I know feeds on a 5 to 7 day schedule.
