I know they aren't as smart as mammals.
But if my mali can recognize his name, his cage mates name and to kiss when he hears that word, I consider him smart.
Our mali's came from Petsmart(my brother used to work there). They get their mali's in from a breeder. This breeder bred his wc mali's and those hatchlings he got, he bred with his friends hatchling mali's. So our mali's are like 4th generation captive bred.
I agree that some reptiles don't know what's what and can't recognize their own names.
But all of our reptiles, Draco, Ares, Apollo, Hades, Kalypso, Iris and Sid Vicious, all look at whoever is saying their name.
I can be sitting down stairs in my brothers room, near his bed (which is about 12 feet from the enclosures) yell out ARES and he'll run to the end of the tank, and look at me.
Not over exaggerating at all, it's the truth. If I say Draco, Draco looks over at me.
It's just my experience with these animals, but I have a close connection with animals becuase I'm NA and it's in my blood to be close with every little animal creature put on this earth.
Also, to note an animals intelligence: Hades, my bearded, is smart IMO. Every time he goes to the bathroom, he covers it up with his coconut hide (too small for him to fit into so he uses it like we would a toilet).
