I figured as much from people I know that owned large snakes. No way snakes alone are going to control a rat population and if I understand that is the point of your posts. Thanks for the info on this.I know this probably wasn’t meant as a serious question but it varies a lot more than that. There is no set schedule with nature obviously but every 7-21+ days is a good average. And only for around 6-8 months of the year. As snakes get older and bigger they start eating less frequently so a snake big enough to eat an adult rat might only be eating 8 times a year.
