Thank you all for your suggestions. I got my scale and was very excited to weigh my babies. They turned out to be <= 75 grams. Cute! Can't wait for them to grow. I got them a couple of small mice and they took them down like nothing. So I'm set to order from one of the three vendors. I'll price them first but I'll definitely order a small bag of small mice, a small bag of rat fuzzies and a small bag of rat pups as suggested. Thanks.
