This is not a valid argument against tubs, because I'm 99% positive that's what this is about. Whether or not snakes have souls, they need to be treated with respect. This includes meeting their needs as best we can. Reading through some of your other posts, I saw that you had shedding trouble a while back, and saw a picture of your setup. You should know that unless you make major changes to that "habitat," your snake is going to have bad sheds, just like that one.
Are we finished with this yet?
