I understand that - but the breeder did not produce these animals and if they were not quarantined before being put for sale than it does not seem like this is a very competent breeder and I would not trust them doing anything with the snake - if the breeder does not even know about quarantining animals before selling them to the public than you can bet that he will not humanely put an animal to sleep - I don't even know if you can get the proper medicines to put an animal to sleep unless you are a vet.
