When to Switch

[200xth]

There's this rule about prey being of 10-15% of snakes weight? And there's the rule about prey width. It shouldn't be any bigger than snakes widest part. I believe that's about it.

The 10% to 15% guideline is really only for younger snakes.

You can make the switch anytime you want, as long as the snake is big enough to actually take the medium rat without difficulty. Some people keep their adults on small rats and they do fine, so there's no rush to make the switch. Better to switch late than too early, IMO.
