What your missing is,
First, this thread is aside from the physical health of your monitor.
Its another part of keeping monitors. Remember, keeping your monitor healthy is suppose to be normal and its suppose to lead to other things. Keeping them healthy is not the sole purpose or goal.
The goal is to achieve what a healthy monitor does. To watch and participate in its life as a healthy monitor.
In this case, your nile appears(only guessing, I am not there) to be treating you with the highest respect. Its treating you like a MALE. That is, the most you can ask for. Not the least. Having your monitor subservent to you is not a very lofty goal. But to have it treat you as an equal is great.
I have stated that many types. Most of my males treat me like another male. They position, they bluff, they act out, Sir, thats what monitors do to eachother.
But that does not mean they are mean and aggressive. It also does not mean they are going to bite you. In reality, your monitor is showing you respect by coming over and giving you a good lashing. hahahahahahahaha, again sir, thats simply a male monitor being a male monitor. If you were not in there and another male monitor was, the very same thing would happen.
I could bore you with lots of stories about male monitors. But one I have fully enjoyed was asking my friends to go in with George my oldest male lacie. I made good friends with a few folks I met here, Rsg and Jefe, to be exact. They did come over and when asked if they wanted to go in with george, they simply were to scared(for their lifes).
You see, George is a male and he does his male things. I had him in a 20 by 20 cage at the time. If you(anything) enterd the cage, he would come flying over at a 100 miles per hour. Or so it seemed. If you had food for him, he charged like some crazed out monster. If not, he still charged and dove at your feet.
The thing is, George is a sweetheart. He does not bite. He simply is being a male monitor. If you have food, he treats you like he would any other monitor, scarce the crap out of you, and hope you drop the food, which works ALL THE TIME, with me and other monitors. You see, thats what healthy monitors do. And it works. It works with other monitors and with people.
What is sad is, once they do not have the strenght to do this bluff, the others recognize that and then they turn the tables and attack and take advantage of the other. You see, its all about being dominate.
You see, thats their design, even if dumb biologist think they are solitary. They have all those behaviors, to puff up, turn sideways, to tail whip, to hiss, to arch up, all such things many other animals have to appear bigger and stronger, WITHOUT ACTUALLY HAVING TO BE BIGGER AND STRONGER. Its how they like so many other animals position themselves. Its what they are and what they do.
The funny part is, if you put another male in there, the same thing will happen, then after a few weeks, they will become great buddies and have all this stuff worked out.
Your not working out being your monitors partner or buddy, your falling for the bluff. Cheers
