That is DEFINITELY a scam! NEVER send money to strangers. So many people have been ripped off.

They had a scam like that before, only they said you won money in a contest and in order to get it, you needed to send them an exhorbatant fee.

ALWAYS put "Adoption Fee" $____. If these people are sincere and really want these cats, they'll donate it. Especially if they're spayed/neutered.

And always make them fill out a contract complete with driver's license, signature, etc. It protects everyone.
