The concept of providing a snake or lizard with articles in their enclosures to provide some "fun" is a very big trap that so many people fall into, in the wild these animals have a home range which sometimes changes gradually, which is no big deal for them, "but" if you take your snake/lizard out of it's enclosure and continually change things around you will in most cases overstimulate the animal with it's new surroundings, we all have animals that will sook if you change 1 little thing in it's enclosure (home range) and stop eating for a couple of weeks till things start looking normal again. Just imagine if you will being taken from your bed and blindfolded, then get taken away for a little while and dumped in an unfamiliar setting, how confusing would it be for you ??? it takes a long while for a snake/lizard to acclimatize to new surrounds which can be seen when you look at all the posts here about "why won't my snake eat" unfortunately this is generally why they are not eating, the stress of new environment. Your snake does not care what you have in it's enclosure as long as it does not change all the time, we human beans like to pretty up and add clutter to their enclosures for our own enjoyment, as long as it gets fed regularly and has a nice warm area to sleep and digest it is happy.
