Yellow Anacondas and all of the other animals listed on the craptastic Lacey Act are -not- banned from ownership.
They are banned from import, interstate transport and sales.
I know a lot of Anaconda owners, along with Retic owners, Burm owners and so on.
You can own and breed the so-called “banned” animals.
You simply cannot sell or move them out of state.
Cats are not a native species.
You’re right about the details of the ban which is about all the Feds could do, considering their jurisdiction.
I’m not sure why you are so adamant about the right of snake owners to avoid any laws or programs that constrain owners from allowing these animals to escape into the wild. And I know some snake lovers would cheerfully keep venomous snakes like mambas, horned vipers, and fer de lance as part of their hobby.
Another good measure would be to require an digital license/id to be inserted into these animals so their owners could be identified if they are found in the wild. Breeders would be required by law to implement this id as a condition of sale. Then, both the breeder and the owner could be held liable if a registered animal got loose.
By the way, society has already put programs in place to pick up, detain, offer for adoption, and eventually put down the cats and dogs you are so worried about. And those animals don’t grow to 20-30 feet in length with a capability to crush and suffocate large animals and humans or to quickly kill with their venom.
