Beautiful babies, congrats!!!
Aaron--Sarae has hit it right on the head. Sand and corn cob are both bad substrates, I think for
anything. I use a corn cob litter for my ferret's litter box, and one thing I've noticed, that sticks in my head whenever I hear of people using it as any kind of bedding, is how it CLUMPS. Corn cob is naturally going to have rough edges, which, in a narrow passage like a snake's gut, locks together to form blockages much easier than a smoother-particle substrate like washed playsand. That by itself is a problem. Then you have the problem that corn cob naturally clumps together, very tightly, very thoroughly, very efficiently, when soaking up moisture (which is why it makes an excellent cat litter). At work, where we use the same stuff for the cats, I've often mistaken pee clumps for very large, litter-coated poops because it's simply such a firm clump. I can only imagine the kind of damage that sort of substrate could do to an animal's gut!
Sorry. Couldn't not put in my $.02.
Again, congrats on the healthy litter, and thanks for sharing, Tom! Sand boas are such cute little worms. I had one at one point, but he never did really eat "right." It was a battle to get him to eat most the time--"Okay, which trick will we try this week..." I don't know if he was just an oddball, or what, but it kind of put me off the worm snakes. Maybe I'll have to try again, and just make sure it's female this time around. Haha.
