Wow, that is one defensive post and one filled with all manner of assumptions.
First off, a 4 foot cage is living proof that you are not thinking about the animal.
lets see, 4ft cage, with a snake that gets over 8 feet. But most likely easily gets six feet. yup, thats plenty of space.
The question is, is that enough space to allow them to reproduce. Yup it is, Again the question was, is that enough space to allow them to make choices as to where they would behaviorally deficate? The answer is no, its not.
Now could it be. Its they cannot even leave one spot, before they hit the wall. If they are average size.
ALso your naive assumptions about they would not make themselves visable. Sorry again, I also feed Pits and they do the same thing. Once you learn them, they come out commonly.
Our most reliable feeding behaviors with pits has been in the winter.
Please sir, how about looking at animals, then the cage, from a third party viewpoint. Not from yours defending everything you do. Simply put, their natural behaviors are based on them moving in a large area. Not a four foot box.
That natural area varies in size depending on need and support, but in ALL cases is larger then your cage.
With all these reptiles, they are areas that support their needs. They have feeding places, sleeping places(shelters) basking places(both in and out), they have places to meet mates, they have places to escape heat, cold, dry and wet. Or find heat, moisture, prey, etc. These areas always are larger then your cage.
Their behaviors are based on finding and using these places, THEY ARE NOT BASED ON YOUR CAGE.
Yet there are things you could test. how about coming up with some fun tests. Like, building a large cage. Then keeping it in the small cage for everything. Then once a day, take the pits and put them in the larger cage for an hour. Then see what happens.
I have a story about pits, most likely before you were born. In the early seventies. I had a pair of het pits. They kept getting out of their cage in my snake room. They did not harm so I moved their hide/nesting box. A wooden box with a lid and a hole cut in it. It was 30 inches longs, a foot wide and a foot high. It was actually some manner of shipping box, I converted into a hide/nexting box.
Well they got out. So I put their box on the floor. Every mourning, they would leave the box and go to the window to bask in the mourning sunlite, then they would go sit between the cages that were on shelves. For some reason, they picked the higher shelves. If I fed them, they would go back to their box. if not, they stayed until dark, then went back to the box.
one funny thing, one day I cleaned out the box and went I put it back, I placed the hole on the opposite side.
When they went back, they kept looking for the hole where it was, they went around and around and around poking their heads where the HOLE was. Of course they finally found the hole and went in. Then they remembered where the hole was. Some days they did not come out.
When they deficated, they normally used an area about three meters from their box. In an opposite corner.
While there is nothing special about this, it does give some insight into what they do.
To me, snakes are the most behaviorally tolerant reptile, as you can shut them in that little box and if fed and watered, can live.
Of course there is a limit to how small the box is before they shut down. The question is, how big does the box have to be before they exhibit a full range of normal behaviors????????
In nature, there is not walls, so the maximum requirement is very large.
The REAL TRUTH IS, as you shrink their BOX, you take away natural behaviors, keep shrinking it, you keep losing behavior, Until the point they shut down.
What your seeing is fine, its real and its important, but, where you go wrong is, you say, they do or did this, you forgot to put, IN A BOX. To that statement. They crapped in their water bowl, IN A BOX. They hide all the time, IN A BOX. etc etc etc.
You do not know or what them, NOT IN A BOX. You see, what they do, NOT IN A BOX, is what they are. What they do IN A BOX, is what you FORCE them to be.
The simple key to understanding is, change the box, and compare change in behavior.
So, why don't you change their box???? This is also key. In reality, you don't for ten thousand of your own reasons that have not one thing to do with the understanding of snakes.
No room, no time, no money, insecurity about your ability to have them work in different boxes, etc. Which has nothing to do with their inherent behaviors.
So, when you say, this is what I saw. You need to add, this is what I saw in a box. Or this is what I saw in a small box. More accurately, this is what I saw in a box thats shorter then the snake is long.
A thought! in nature, in field work, to make a statement about movement. Like X individual left point A and moved to point B. The snake must travel more then its own lenght. To not travel more then its own lenght is not really moving anywhere is it????? So in all reality, your cage is like a wild snake trapped in a hole, a hole they cannot get out of.
Please think about this, and stop with your rationalizations. Please look at your statement about whats in your box, then compare it to whats in their natural box, outside. I hope you feel silly. I know I do when I think about them, in a box.
And no, I am not anti keeping them, I am just anti thinking you know them from what they do in a prison cell. Think sir
