Sorry, but It is not factual because those are not facts. How many lizards do they eat? Are they all eating lizards? Do the ones eating lizards do better or worse than ones not eating lizards? Are those the ones that are reproducing well or are they dying younger from health problems? What are their blood values compared to those not eating lizards? You are not following the chameleons through their life to see what the effect actually is, and you don't even know how often it occurs or what effects it has. Just seeing a few isolated occurrences does not mean the entire population is doing the same, and it certainly doesn't indicate that it is good, or bad, for them. What if the population is only expanding because the first clutch of eggs hatches and then all the adults die of kidney failure before laying the second clutch? I am not suggesting that is the case but there is more to scientifically evaluating a problem than just seeing something happening a few times and "knowing" that it's beneficial to all chameleons everywhere. Facts are gained by looking at the whole picture. The only fact you've offered is that is does happen. Says nothing about the value of it one way or another.
