The captive-bred bearded dragon is a whole different animal - super sweet, very cuddly, probably the most docile reptile out there, which is a big reason why they're popular as a beginner pet for first-time herp owners. I don't know if they're neurologically capable of "loving" their caretaker in the same way that a dog or a horse can, but they definitely are capable of bonding with them to a certain extent.
I'm not sure if this really applies to the smaller, dumber reptiles, but while it has long been thought that the reptilian brain wasn't capable of the sort of complex behaviors mammals have, the crocodilians in particular turn out to be a lot more intelligent than previously thought, being capable of cooperative hunting and other behaviors indicative of being capable of thinking and planning.
More surprisingly, they have even been witnessed doing things that at least look like altruism.
If you own an exotic snake you should be required to have the antivenin already, or show that your local hospital has it in stock. Which is usually the case for native species. If you want more exotic shit, procuring your own should be mandatory.
You should also be forced to have vast amounts of insurance to cover the strict liability applied to those who keep inherently dangerous animals. This should be in the millions. Underwriters will not underwrite for a mammoth retard like this Leibowitz faggot.
Better to just maintain a very large blacklist on a species-by-species basis. It's easier to prosecute when the law says in black-and-white, "you cannot own a king cobra as a private citizen, you fucking retard, see chapter 3 section 14 bullet point 48 of the LEIBOWITZ statute" (a/k/a the "Law Embargoing Idiot Breeders, Ophiophiles, and Wiggers from Importing Toxic Zoology").
The problem with this is that you risk either having gigantic thousands of pages long laws just on snakes, plus if you forget to put something on there, some moron will go get that exact thing, because being that specific in law with an enormous list inherently implies that anything not prohibited is permitted.
The same risk applies to a list of permitted animals, but in the other direction.
The usual statutory approach is to put things in broad terms, but then you have the administrative hazard of unelected administrative agencies essentially making completely arbitrary and unreviewable decisions. This is somewhat diminished at least on the federal level with SCOTUS's recent abolition of
Chevron deference (the general principle applicable until recently that administrative agencies effectively had carte-blanche to interpret the statutes they enforce to an insanely broad degree), but probably still applies to state law.
Maintaining giant blacklists (or whitelists) on a statutory level leads to incredibly unwieldy state codes, and allowing administrative agencies to do so willy-nilly presents equal or even worse menaces.
