Actually - I got them in this week. They are about 20-22 inches in length.
I have already held them both for about a minute or two(don't want to stress them out to much) to do a basic inspection. They are pretty laid back, easy-going and docile.
And today I actual feed them F/T fuzzy "crawler" mice. They had been taking live fuzzy/crawler mice. But I just had F/T - so I heated the mice to about the same as the normal body temps for mice 99-100 F. Then wiggled them in front of the snakes for a minute or two. They both ate them just fine - I watched them as they ate the mice.
