At 14 grams (my 2 smallest) they each eat 2 pinkie African soft furred rats a week.

At 20 grams one of my Kenyan Sand Boas eat 1 rat pinkie every week.

At 60 grams one of my other ones eats 3 - 8 frozen thawed pinkie mice a week.

My biggest Kenyan is 282 grams and she eats either 3 rat pinkies, 2 rat fuzzies, or ONE small rat a week.

We have 12 Kenyan Sand Boas total. Ranging from 2 months old (our first clutch) to 3 years old. I really hope this information helps.
