Defecation concerns.

Little over a week in with having my snake. I feed it day 1, then 4 days later, then four days later. I haven’t noticed any poops. Should I be concerned?

Depending on what you are feeding compared to the size of your snake, that's probably too often. Sometimes they take a while to poop and usually it's not a cause for concern, but if he hasn't gone since you got him, I'd give him a bit of a break from food, maybe a week.

Gotcha. I was just seeing you should feed the babies twice an week. The packaging says they are small mice. But I’ll give em a break. Will they feed even if they aren’t hungry?

Depends on the BP.

Compare the mouse thickness to the thickest part of your snake. If the mouse is about as big as that, 5-7 days between would be better. If the mouse is quite a bit smaller, you can either feed twice a week or two mice at a time once a week.
