Are ratsnakes constrictors?

[Aes_Sidhe]

It also states poisonous snakes - which there are only two. I guess venomous snakes are perfectly legal.

Uhh There are actually poisonous Snakes ?? With Ones ??? (I believe You talking about poisonous meat after human consumption)

Edit:

To OP: And If they specifically state family Boidae there You are fine with Pythons as well because the are form family Pythonidae...
and If You wanna play with them even more You Should be fine with most Central American Dwarf Boas as well because they are from family Tropidophiidae
