I normally feed my MBK four fuzzies once a week. She gobbles them down with no problem,
Since she regurged I would wait a few days and feed a pink. If she holds it down wait a few more days and then go to a fuzzy. Then wait a few days again and the next meal go to a weaned mouse (hopper, crewcut or whatever you call them). If she regurges any of the above get some flagyll* or take the snake to an experienced snake vet. Find a vet that keeps colubrids themselves or you will be stuck with a high vet bill.
*flagyll must be administered once every ten days (2x) with no food offered in between.
but this week she regurgitated all four of them in one nasty shot
how much time between feeding and regurge?
Go to a single large food item like a two weaned mice.
My question is can i be feeding her too much?
no
Or should i give her more than seven days in between feedings?
no
She's a normal heathly two year old about 36 inches long
Four fuzzies is not very nutritious for a 36" snake. After you figure out the problem switch to larger mice.
