upsizing food

Been feeding small rats that are averaging 66-72g. My snake is 1.5 years old and weight is 970g. Should I increase feeding from every 10 days to 7? And when I'm done with this collection of rodents, should I order medium size rats? It's gonna be a while before they're gone. I probably have about 6 months worth of small rats.

Small rats are all you will ever need for the rest of your snakes life.
Really the only time you would feed mediums is for a breeding female to pump her up a little.
Your 10 day feeding schedule is also good.

I was just curious. It seems like lately he's active more quickly after he eats. I just don't want to not give him enough.
