Please understand, reptiles grow very fast, or not. They can grow very slow, or not. Reptiles are dependant on conditions, and food resources for their growth. Ifs its dry out, they stop eating(no matter if foods available). Of if foods scarce, they drop their temps, it does not matter what month or season it is. Thats in nature.
In captivity, their growth is dependant on how well you take care of your monitor. I have raised and bred many many species, from the smallest to some of the larger species. And all can and have grown up in under a year and produced. or not.
I agree with Shvar, your term powerfeeding, is a term used by the naive. That is, by folks who do not understand reptiles. That is unless they are forcing a individual that does not want to feed, to feed. Like force feeding. Force feeding with a caulking gun would be power feeding, you know, against the will of the monitor.
If the conditions allows a monitor to be hungry, then feeding it is normal. If it was not in your cage it would be looking for food. If your monitor is hungry everyday, then its normal to feed everyday. Do you understand that.
As I mentioned in the subject box, many people would think feeding several times a week is power feeding. Those people may only feed once a week and call that normal. There temps and moisture levels may only allow feeding once a week. So there monitors may not want to feed any more then that. Those folks would not understand a monitor wanting to eat several times a day. But then, their conditions suck.
In my experience and opinion, young growing monitors, givin a choice of conditions, will not only feed everyday, but often several times a day. That is, they are givin temperature choices both above and below, their useable temps.
Now, the problem is with adult non growing monitors, these many only need food once a week or less, but they are hungry everyday(mainly males) So feeding a non growing monitor many times a week will result in a obese monitor. Here is where your being a keeper is important, you have to decide when that point is reached and react to it.
So, its up to you to decide whats best for you and your monitors goals and conditions.
Personally, its sad to see them grow out of the baby stage. But, thats what they do. FR
