Okay well just to give you a quick idea of what I know.
Lizards: you may keep-leopard geckos, blue tonged skinks, rock monitors, water monitors, bibrons and turners geckos aswell as giant ground geckos and african fat tailed geckos.
Snakes: You may keep almost all the indigenous harmless snakes excluding the rare house snakes such as fisks and yellow bellies, almost impossible to get permits for exclusively gecko/lizard feeders such as wolf snakes, natal greens, etc.
Most of the american and asian ratsnakes may be kept. Aswell as the american kingsnakes.
Most pitvipers aren't allowed, except for purple mangrove vipers, eastern and western diamond backs, copperheads and white lipped tree vipers.
Almost all indigenous venemous snakes may be kept, including black and green mambas, all indigenous adders(excluding some rare dwarf adders),all indigenous non spitting cobras, rinkhals and mozambique spitters. No other spitters are allowed.
No exotic cobras allowed and very few exotic adders allowed.
Most boas and pythons are allowed. icluding rainbow boas(columbian and brazilian), boa constrictors, yellow anacondas, retics, burms, balls, carpets etc etc.
I have porobably left loads of stuff out but this is just a rough idea of what we can and cant keep this side of the eastern cape. By no means is this a complete list
