Thanks to everyone for their feedback on the "should I/shouldn't I" house Talyn and Q together issue. I've considered the pros and cons extensively. I even e-mailed a man who has 68 adult Rainbow Boas (12 sub species!) www.rainbowboa.co.uk .I figured he would have the best idea of whether or not 2 unrelated adult females could be housed together in a terrarium 5ft x 2.5ft x 4ft high. He said to try it: it will be immediately obvious if they are not comfortable with eachother and if that is the case, they will need to be separated. Respiratory infections, as Rachel pointed out, are usually the result of improper husbandry: in which case, both snakes would suffer. I always feed in a separate feeding bucket and although it will be difficult to tell who left me which feces and urates, I thought it would be worth trying. I cleaned out the whole terrarium and sterilized or replaced everything in it with new stuff. Then introduced them at the same time. They get on fine! In fact, they always seem to want to be together! I've provided them with 2 cool hides, 2 warm/moist moss boxes and one warm dry hide. They seem to prefer to squeeze together under one hide than use separate ones! When I take them out individually and then put them back in on opposite sides of the terrarium, they immediately look around for the other one and slide over there under, over, in between etc. I don't know about calling them "social animals" but they seem to feel more comfortable together than apart. Here are two pics: The first was what I found when I took away the cool hide box this evening. The second is them squished up together in the warm moss box just after I took them out for weighing and a bit of handling.
