So on 8/4, I measured my corn snake, and she was 20" long. Today (9/18), I measured her again, and she's now 24" long. She's gained four inches in a little over a month. Is this right? She's a yearling, and was on a maintenance diet at the reptile store until i got her in July, so she was smaller than she could have been. I've got her up from small fuzzies, to hoppers, and she looks good. But I was surprised to see four inches in growth in such a short time.
