Now now, be nice. Everyone here is entitled to their own opinion, so no need to get hot headed up there! =P
However, yes, they CAN feel emotions, just like every living thing animal on this planet, which makes them unique to every other living thing in that respect. They CANNOT feel human emotions related to envy, love, resentment, speak an oral language, have culture or religious beliefs, awareness of space and time, etc.
You CAN read the intentions and overall disposition of a reptile through body language, such as the eyes, overall body posture, mouth, head disposition, tail orientation, etc... but these are guesses based off previously examined and experienced behaviors, which are accurate in most respects. These behaviors determine if the animal is comfortable, upset, hungry, etc. These are not however relations that display love, resentment, or that tomorrow is Monday and the next day Tuesday, etc. It is such that makes them independent animals and 'wild'.
This does not mean however you cannot have a relationship with your reptile, which is why they have remained (for one primary reason) in the pet trade for so many years, especially in respects to bearded dragons who have been known to have a unique interest to those who care for them. I LOVE Aussie and Calypso and, I'm pretty sure that in my mind while I feel a self accomplishment and appreciation for all of the care I've given Aussie in particular who has been to the vet nearly 13+ times and cost me nearly $1200, that he is unable to comprehend and appreciate the same respect. But it doesn't matter. I love him =) even if he doesn't 'love' me back in the same manner. His 'love' however is represented in the fact that he is still living and behaving like a normal, semi tamed reptile- heck, he's lived 4 years through several dozen diagnoses, needles, syringes, etc where most would have surely perished. Their wild and exotic behavior is what should be appreciated. The fact that you, as a human being, can be a part of that and appreciate what they represent to you is all that you need. Obviously, this website represents that. And through human imagination, which is much appreciated and welcomed, bearded dragons have become the most popular and loved exotic pet.
