Anybody wanting a tame animal should buy a dog or a cat.

Some monitors may seem tame as adults, but get them in a stressful situation or near food and you quickly realize that this notion of "tame" is wishful thinking.

Getting a monitor lizard to the point where it's a tolerable captive takes time and patience. People looking for a cold-blooded replacement for a dog are going to get frustrated with the time and effort required to gain a modicum of "trust" from a varanid.

This whole idea of "taming" varanids bothers me. People should keep them because they are fascinating animals, not as an exotic alternative to a poodle.
