I see no reason to feed prey that big unless you're trying to get the animal to breeding size.

Following the 10-15% body weight rule of thumb, 45 grams would be the highest to go. You say it's not THAT much more, but it's nearly DOUBLE 30 and literally DOUBLE what the snake is used to.


CAN the snake eat it? Of course.
SHOULD the snake eat it? Prob not.

Just buy appropriately sized prey and save those for later.
