Thank you much. The substrate is "for reptiles and perfect for nesting or breeding snakes" as it says on the bag, and I can't see any sand at all in it, so it might have to include that in the materials because some might be present. Just was trying to see if anyone had a problem with this brand.

I think I will let him get a bit use to the new environmental changes. I am going to get one of those ionic breezes because me and my fiance are slightly allergic to cats (her slightly more) and it will cut down on the animal odor and dander in the air a bit to help out.

The kitten doesn't know the snake exists, and I hope to keep it that way. The snake does not move enough to hold the interest of a kitten. When the kitten gets older she might "discover" the snake. I plan to keep them away from each other especially when the snake is out. And I always wash my hands before and after handling. Jub Jub's nose is amazing for smelling food though. Hopefully next week I can start to handle him again, as I'm gonna give him some settling in time.
